1.	What does the pyramid of energy indicate because of which it is said to be the best representation of an ecosystem?(a) Number of all plants and animals(b) Rate of respiration(c) The total rate of photosynthesis(d) The rate of energy flow through the food chainI have been asked this question in semester exam.My enquiry is from Ecological Pyramids in chapter Ecosystem of Biology – Class 12
Answer» Correct ANSWER is (d) The rate of energy flow through the food chain The EXPLANATION: The pyramid of energy is said to be the BEST representation of an ecosystem because it indicates the rate of energy flow through the food chain. DEPENDING upon the nature of the food chain, the pyramid is always UPRIGHT.
