Question

assume npp = 1% of sunlight in this specific food chain, which level has the most energy available to it? tertiary consumers secondary consumers primary consumers producers

Explanation:

In ecological food chains, energy flows from sunlight to producers first. Producers capture 1% of sunlight as net primary productivity (NPP). Energy is lost at each subsequent trophic level (only ~10% transfers to the next level), so the lowest trophic level (producers) has the most available energy.

Answer:

Producers
