Question

what can we learn from comparing biomass amounts at each level? (select the three correct answers.) (1 point) a large amount of energy is lost between levels. biomass is spread almost evenly among all the levels. the transfer of energy between all levels works very well. the producers depend directly on consumers for their biomass. an ecosystem can support far more producers than consumers. the least amount of biomass is available for top meat - eaters.

Explanation:

1. Energy transfer between trophic levels is inefficient, with ~90% lost as heat, waste, or used for metabolism, so a large amount of energy is lost between levels.
2. Due to energy loss, biomass decreases at each higher trophic level. This means ecosystems can support far more producers (base level with most biomass) than consumers.
3. Top carnivores are at the highest trophic level, so they receive the least amount of energy transferred up the chain, resulting in the least available biomass for them.

Answer:

A. A large amount of energy is lost between levels
E. An ecosystem can support far more producers than consumers
F. The least amount of biomass is available for top meat-eaters.
