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%

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.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
