Question

compare how nutrients move through ecosystems versus how energy moves. *
your answer

Explanation:

Nutrients cycle in ecosystems through biogeochemical cycles like the carbon - cycle, nitrogen - cycle etc., being recycled between living organisms and the environment. Energy, on the other hand, enters ecosystems as sunlight, is converted by producers through photosynthesis, and then flows through trophic levels as organisms consume one another. Energy is gradually lost as heat at each trophic level and does not cycle back.

Answer:

Nutrients cycle, while energy flows in one - direction and is lost as heat at each trophic level.
