Energy Pyramids represent the food chain energy and population sizes. Which statement is NOT true.
A. 90% of available energy is lost between each trophic level
B. Populations are smaller as you go up the pyramid
C. Heat is only lost at the consumer levels
D. Decomposers play a role at all trophic levels
D is false. Decomposers are a separate level in of itself, so as far as “decomposers play a role at all trophic levels” go, the answer choice would be invalid, and thus forth is the correct answer. All other answers seem to be valid.
