Question

below is a food web from shenandoah national park, a forest ecosystem in virginia.

in this food web, which organisms contain matter that eventually moves to the bolete fungus? select all that apply.

beaver
parasol fungus
black bear
pine vole
persimmon tree

Explanation:

In a food web, matter moves through the ecosystem. Decomposers like boletes break down dead organisms. The beaver, black bear, pine vole, and persimmon tree (when they die) will have their matter decomposed by the bolete fungus. The parasol fungus is another decomposer and its matter would not move to the bolete fungus in the way the question implies (as they are both decomposers and not in a predator - prey/decomposer - consumed relationship in this context).

Answer:

beaver, black bear, pine vole, persimmon tree
