Question

The figure shows an energy pyramid for an ecosystem. What happens to the amount of energy in the pyramid as it moves up through the different levels? A) It increases by a factor of about 10%. B) It decreases by a factor of about 90%. C) It increases by a factor of about 90%. D) It decreases by a factor of about 10%

Answer 1

Answer: The answer is D

Step-by-step explanation:

I got it right on edge

Answer 2

B) It decreases by a factor of about 90%.

Explanation:

When we move in the upward direction in the energy pyramid of an ecosystem, the amount of energy is decreases. If a producer contains 100 % energy, so only 10 percent energy is transferred to the body of primary consumer and the rest 90 percent is lost as heat energy. And again when primary consumer is eaten by secondary consumer, only 10 percent of energy is transferred and the remaining energy is lost as heat energy and so on.
