Question

Quizplus · Accepted Answer

In a typical energy pyramid, only about 10% of the energy from one trophic level is passed to the next level. If trees are at the base, then primary consumers (like frogs) would receive about 10% of the energy, secondary consumers (like spiders) would receive about 1%, and so on. Therefore, spiders, being likely two levels above the trees, would receive about 1,000 units of energy from the original 100,000 units contained within the trees.
