Question

study the food pyramid. which trophic level has the greatest total amount of energy to transfer to the next level?

Explanation:

In a food pyramid, the base - the producers, have the most energy. Grains are producers which convert solar energy into chemical energy through photosynthesis. As energy is transferred up the trophic levels, only about 10 - 20% of the energy is passed on due to energy losses in metabolic processes like respiration. So the lowest trophic level (producers) has the greatest total amount of energy to transfer.

Answer:

Grain
