In a deciduous forest ecosystem, which of these organisms would be a decomposer?
a) algae
b) lichen
c) mushroom
d) oak tree

In a deciduous forest ecosystem, mushroom would be a decomposer.

A decomposer is an organism that breaks down decaying organic material. Decomposers obtain their energy by ingesting the organic material they are decomposing. Mushroom (a decomposer) is a fungus that release enzymes which decompose dead plants and animals. Mushroom can be found in a deciduous forest ecosystem (an ecosystem that contains mainly broad-leaved trees whose leaves fall during one season).

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
