Question

The amount of available energy changes between the trophic levels found in a food chain or energy pyramid.

How would the amount of available energy differ in the trophic level of the mouse compared to the trophic level of the hawk?

a. Available energy would increase from the mouse to the hawk.
b. Available energy would decrease from the mouse to the hawk.
c. Available energy would initially increase from the mouse to the hawk, and then decrease over time.
d. Available energy would remain the same from the mouse to the hawk.

Answer 1

The answer is b. Available energy would decrease from the mouse to the hawk. The mouse is at a lower trophic level compared to the hawk. Energy is lost from lower trophic levels to higher trophic levels, as assimilation from one level to another is inefficient, and energy is lost at each level due to respiration and excretion.

Answer 2

The correct answer is: Leaf to Mouse.
