Definition of Ecosystem Online Biology Tutors Tutorpace

Definition of Ecosystem Online Biology Tutors Tutorpace Ecosystem is a self-sustained and self-regulated segment of nature or landscape where living organisms interact and exchange materials amongst themselves and with their physical environment. The term was coined by Arthur Tansle.Ecosystem can be large or small, temporary or permanent, natural or anthropogenic, terrestrial or aquatic, complete or incomplete. Ecosystem has a number of abiotic (nonliving)and biotic (living) components, all of which are interrelated and interact with one another. There is a regular inflow of energy from outside which is trapped by plants along with inorganic nutrient to form food. This is the primary productivity of an ecosystem. The food along with its contained energy passes to other biotic components. There is dissipation of energy at every step of transfer and functioning of biological systems. It is lost to environment. Inorganic nutrients are not lost. They are released for recycling when organic matter and inorganic wastes undergo decomposition. Because of regular inflow of energy and its dissipation with a regular input and output of nutrients, an ecosystem is called open system. On the basis of nutritional requirements biotic components of an ecosystem are divided into three groups-producers, consumers and decomposers. Producers in an ecosystem are the green plants because they have got the capacity to prepare their food using solar energy by photosynthesis. Consumers are those organisms that consume the synthesized food or producers. The consumers depend on producers directly or indirectly. Decomposers are the saprophytic microorganisms which obtain nourishment from organic remains.

What is Quotient

What is Quotient Division is one of the 4 basic and most important operations in math. In the process of division of two numbers, one number gets divided by the other number. The answer or the result we get in the division process is known as the Quotient. So quotient is the number which is produced when a certain number is divided by another number. If the given number is being divided by its factor, then in that division the remainder produced will be 0 and the answer is the quotient. Example 1: What is the quotient when the number 48 is divided by 4? Here 48 is being divided by 4, and this can also be written in the fraction form as: 48/4. Here the number placed on the top (or in the numerator) is 48, and the number placed in the bottom (or in the denominator) is 4. Using the long division process, 48 is divided by 4 and the answer is 12. Hence the quotient when 48 is divided by 4 is 12 == 48/4 = 12. Example 2: What is the quotient when the number 63 is divided by 7? Here 63 is being divided by 7, and this can also be written in the fraction form as: 63/7. Here the number placed on the top (or in the numerator) is 63, and the number placed in the bottom (or in the denominator) is 7. Using the long division process, 63 is divided by 7 and the answer is 9. Hence the quotient when 63 is divided by 7 is 9 == 63/7 = 9.

Online Slope Finder Tutors

Online Slope Finder Tutors Slope is found by the change of y axis co-ordinates over the change in x axis co-ordinates. Slope of a straight line gives the orientation of the line with respect to the co-ordinate axes. Slope is defined as rise over run. The slope of a line is the same for all the points on the straight line. The slope of the line is used in different formulas such as slope intercept form, slope point form etc. which help in writing the equation of the straight lines. Example 1: Find the slope of the straight line passing through the two points (5, 2) and (0, - 3)? Solution: Given are the two points (5, 2) and (0, - 3) from a straight line. Slope = change in y coordinates / change in the x coordinates. Here for the given two points slope = (-3 (2)) / (0 (5)) = -5/ -5. Slope = 5/5. Simplifying, slope = 1/1 Hence slope of the straight line passing through the given points = 1. Example 2: Find the slope of the straight line passing through the two points (10, -3) and (6, 4)? Solution: Given are the two points (10, -3) and (6, 4) from a straight line. Slope = change in y coordinates / change in the x coordinates. Here for the given two points slope = (4 (-3)) / (6 (10)) = 4 + 3 / 6 - 10. Slope = 7/-4. Simplifying slope = -7/4. Hence slope of the straight line passing through the given points = -7/4.

A Guide to Reviewing MCAT Practice Exams

A Guide to Reviewing MCAT Practice Exams MCAT Medical School Admissions When studying for the Medical College Admissions Test (MCAT), most students tend to focus on studying through content review and reading preparation books. However, an essential method for preparing for this exam is taking numerous practice tests to prepare for the format as well as the arduous length of the exam. A critical portion of this practice is to effectively review exams in order to assess strengths and weaknesses in both content and testing strategies. Below we will discuss tips to optimizing your practice exams and strategies for reviewing them. Track exams on a spreadsheet Just as an athlete tracks their progress in training, a student should track their progress on practice MCAT exams. This tracking can be as simple as recording the composite and section scores in an excel sheet or it can be more complex. Students may record scores and progress by breaking down their performance in various content areas, timing, and other factors. It is truly up to the student as to how they mark their progress. However, most students tend to benefit from tracking more factors and analyzing their progress in terms of timing and content areas. Recording progress also prevents students from accidentally retaking the same test. It also allows them to notice overall trends in exams from different companies and in their performance over time. Overall, this process gives students a definitive way to measure progress and decide if they are meeting their goals. Review content weaknesses by section After completing a practice exam and recording scores, students typically benefit most from looking an analysis of scoring in different content areas. Most test preparation companies will include this feature in their practice exams. A detailed review of percentage correct in content areas gives students an idea of what areas within each section they are struggling with. Ideally students should make note of these areas and target them for review in the weeks prior to their next practice exam in order to see if poor scoring is due to content weakness or a strategy issue. Content weakness is typically resolved through additional studying, whereas strategy can be developed from encountering the topic through additional practice problems and passages. Review the test question by question While it is tempting to review only questions that were marked as incorrect, a great deal of learning can occur through reviewing an entire MCAT test. Some answers to questions may have been guesses or correctly answered but with the wrong application of concept knowledge. This can cause incorrect answers on similar questions later if not identified and corrected. Furthermore, reviewing correct answers reinforces material and serves as a quick review over a large amount of content. Reviewing every question on a practice exam is essential to large improvements to scores and scoring in the higher percentile ranges of the MCAT. Take notes In addition to reviewing the exam, students should be making notes on content to review. Whether they are notes inserted directly into their review books, personal written notes, or a separate Microsoft word document, they should be easily accessible for review. These notes should be reviewed within a week of taking the practice exam to reinforce the concepts they struggled with. In addition, these can serve as last minute study resources prior to their official test date. This allows students to recall topics they continually struggled with and gives them one last chance to review them prior to their exam. Evaluate your performance Finally, students should develop a method of self-evaluation on performance. Some students choose to rate their performance prior to seeing their score report and compare that with their scores after. This allows students to develop a standard on how they perform on test day. Some students prefer to assess their performance only after reviewing the test in its entirety so that they can decide whether their score is a matter of content weakness, timing, or strategy. Be wary of the second method, as students tend to be more generous in hindsight. It is easy to blame a low score on timing or changed answers. Students should make sure to hold themselves accountable and be honest with themselves in how they are performing on their practice exams. This practice is a good way to subjectively measure progress and assess preparedness for the exam. A final word of advice on practice exams… Practice exams are a great resource to prepare students for test day. Make sure as you approach test day, you do not overwhelm or exhaust yourself with too many practice exams. The week prior to your exam should be a rest week where you review notes and old exams but do not take any new tests. This rest is vital to refreshing your brain prior to the exam. Make sure you take time to rest so that you perform well on your test! About the Author Jordan Salley is one of MyGuru's most accomplished MCAT tutors. Click here to learn more!

GCSE Poem Analysis The Yellow Palm by Robert Minhinnick

GCSE Poem Analysis The Yellow Palm by Robert Minhinnick English Literature GCSE Poem Analysis: The Yellow Palm by Robert Minhinnick What is it about? The poem is a colourful but sensitive account of various sights in Baghdad, each affecting to the poet, who travelled there in the late 1990s.   It describes the results of violence and implies a dreadful explosion without directly showing the reader. The Yellow Palm by Robert Minhinick As I made my way down Palestine Street I watched a funeral pass - all the women waving lilac stems around a coffin made of glass and the face of the man who lay within who had breathed a poison gas. As I made my way down Palestine Street I heard the call to prayer and I stopped at the door of the golden mosque to watch the faithful there but there was blood on the walls and the muezzin’s eyes were wild with his despair. As I made my way down Palestine Street I met two blind beggars And into their hands I pressed my hands with a hundred black dinars; and their salutes were those of the Imperial Guard in the Mother of all Wars. As I made my way down Palestine Street I smelled the wide Tigris, the river smell that lifts the air in a city such as this; but down on my head fell the barbarian sun that knows no armistice. As I made my way down Palestine Street I saw a Cruise missile, a slow and silver caravan on its slow and silver mile, and a beggar child turned up his face and blessed it with a smile. As I made my way down Palestine Street under the yellow palms I saw their branches hung with yellow dates all sweeter than salaams, and when that same child reached up to touch, the fruit fell in his arms. Overview Although the poet says he travels down the street, really we see a parade of characters come past us: a funeral, the faithful responding to the muezzin’s call, ex-soldiers begging for money, the river, a missile and a beggar child.   The missile must explode, but we only know because of the verb ‘fell’ as the dates collapse into the outstretched arms of the beggar.   The poet hides the violence with the picturesque scene â€" but not entirely. Form and Structure The poem is written in six stanzas of six lines, in ballad metre.   The rhyme pattern (which can be notated xaxaxa) is an extended version of simple four-line ballad, which was originally a folk-poem form, but Minhinnick is following in the footsteps of poets like Wordsworth and Auden and many others who have chosen to use the strongly rhythmical pattern to tackle serious subjects.   By doing so in six-line stanzas he has a little more time to develop each image, while still staying true to form and changing the focus regularly. There is a very strong rhythm to the form, with four stressed beats in the first of each two lines and three in the second, leaving a pause that readers or listeners associated with ballad form.   This means that although when read aloud the poem might go faster or slower, it won’t substantially change the emphasis a reader places on the words.   Sometimes there are conflicts with the natural stresses in words, when the rhythmic scheme (the metre) wants us to stress them one way and their normal pronunciation prefers another, such as ‘dinars’ and ‘beggars’.   However, this uncertainty challenges each reading to be thoughtful and considerate of the meaning of the words when perfectly regular verse would not. Rhyme is very important in ballad verse and it’s worth looking at the patterns the poet creates.   In order, the rhyming words of each stanza are ‘pass, glass, gas’; ‘prayer, there, despair’; ‘beggars, dinars, wars’; ‘Tigris, this, armistice’; ‘missile, mile, smile’; ‘palms, salaams, arms’.   The strongest rhyming of the three is arguably the last, meaning that the poem ends with a strangely warm and comforting group of words, quite at odds with the violence unleashed by the explosion of the missile. [If you are a northerner and pronounce ‘pass’ and ‘glass’ with the same short ‘a’ as ‘gas’, then the first trio really rhyme very strongly indeed, which would work to establish the regularity of the verse form.] ‘Tigris, this, armistice’ are a diverse group of words, including one of the very few proper nouns in the poem and coupling it with an abstract noun of particular intangibility.   No-one can touch an ‘armistice’ and it is even hard for troops to maintain one.   In contrast, the wide Tigris has been written of and spoken of for centuries: its existence cannot be in question. Language We’ve already begun to consider the words Minhinnick chooses, so now we might focus on the strongest of his word pictures.   The dates, ‘sweeter than salaams’, mix a literal sweetness of the fruit with the metaphorical sweetness of the welcome the poet has found in Baghdad.   The smile of the beggar child with which he ‘blesses’ the passing cruise missile shows how innocent he is, and how undeserving of suffering. The ‘cruise missile, / a slow and silver caravan / on its slow and silver mile’ has a really sinister air when described like this.   ‘Slow’ is of course impossible for a flying weapon, even though the poet repeats it.   Perhaps he is thinking about the way time seems to slow when we see something awful like a bomb about to hit...   Giving the missile possession of the mile by the little word ‘its’ also gives the weapon a life of its own.   We have to ask why ‘silver’?   The missile might be silver, but the mile it has travelled...   Unless that route has been marked with a streak of fast-moving metal, or perhaps if that silver has again been transferred in our mind.   It might be tempting to say that this is ‘just poetry’, but the power of this poetry is that it sparks a hundred other ideas and thoughts in our head.   And to call the missile a ‘silver caravan’ is a dreadful joke: it doesn’t bring prosperity, but pain and grief.   It might have been expensiv e and valuable, but nobody wants it to arrive at the market on Palestine Street.   The people there have already seen enough suffering.
