Question

in a healthy ecosystem, which trophic level should have the most energy?
primary consumers
secondary consumers
producers
tertiary consumers

Explanation:

In an ecosystem, energy flows from producers to consumers. Producers, like plants, capture energy from the sun through photosynthesis. As energy moves up the trophic levels (primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers), about 90% of energy is lost at each transfer. So, producers have the most energy.

Answer:

Producers
