In an energy pyramid, which level has the most available energy?

Question

producer level

first-level consumer level

second-level consumer level

third-level consumer level

Answer 1

The producer level has the most available energy in an energy pyramid as producers (such as plants) receive energy directly from the sun through photosynthesis and convert it into chemical energy, which is then available to the consumers that eat them. As you move up the food chain, there is less and less energy available as it is lost to metabolic processes, heat, and other inefficiencies.
