Question

food webs: mastery test
if these organisms were arranged in an ecological pyramid, which level would retain the least usable energy from the sun?
lion
wolf
owl
zebras
rabbit
green plants

Explanation:

In an ecological pyramid, only ~10% of usable energy transfers between trophic levels, with energy lost as heat at each step. The highest trophic level (top predators) receives the least remaining energy from the original solar energy captured by producers. In this food web, lions are the top predators, feeding on both primary consumers (zebras) and secondary consumers (wolves, owls), placing them at the highest trophic level.

Answer:

The lion level (top predator trophic level) would retain the least usable energy from the Sun.
