Question

1. biomass increases as you get to higher trophic levels. a. true b. false 18. there are rarely more than 5 trophic levels because energy loss is so great at each level. a. true b. false

Explanation:

In an ecosystem, energy loss at each trophic level follows the 10 - 20% rule. As energy is lost, it becomes difficult to support more than 5 trophic levels. Biomass generally decreases as we move to higher trophic levels due to energy limitations.

Answer:

1. B. False
2. A. true
