Question

In an ecosystem with four levels—producers, primary consumers, and two higher-level consumers—describe where the decomposers operate relative to the other trophic levels. Provide at least two examples of organisms at each level.

Answer 1

The decomposers would be at the very top trophic level. Grass (Producer) is eaten by a mouse (level one consumer) then the mouse is eaten by the snake (level two consumer) then the snake doesn't have enough energy to continue and dies, then leaving the decomposers at the top like fungus to feed off that and return the nutrients to the producers so they can grow.
