Question

What happens to the amount of available energy as energy moves progressively through successive trophic levels?

Options

• It progressively returns to autotrophs.

• It is progressively diminished due to energy loss at each stage.

• It becomes solar input at each stage.

• It remains the maximum concentration at each stage.

Answer 1

Energy is lost at each stage of transfer through successive trophic levels. Therefore, the total amount of available energy progressively diminishes.
