Question

which trophic level in the following food chain has the most available energy? a. the tertiary consumers (sharks) b. the secondary consumers (the red fishes) c. the primary consumers (the green fishes) d. the primary producers (the algae)

Explanation:

In a food - chain, energy transfer follows the 10% law. Primary producers, like algae, capture energy from the sun through photosynthesis. As energy is transferred from one trophic level to the next, only about 10% of the energy is passed on, with the rest being lost as heat. So, the primary producers have the most available energy.

Answer:

D. The primary producers (the algae)
