in a healthy ecosystem, which trophic level should have the most energy?

In a healthy ecosystem, the trophic level that should have the most energy is the producer level. Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis, forming the base of the energy pyramid. Energy decreases progressively at higher trophic levels because only about 10% of the energy at one level is transferred to the next level, with the rest lost mostly as heat through metabolic processes. Therefore, the greatest amount of energy is concentrated at the producer level, supporting all other levels above it.
