Which best describes the organisms that would recycle decaying matter back into the mountain ecosystem?

• The mushrooms because they are decomposers and break down matter to return to the ecosystem.

• The Sun because it provides all the energy required for the organisms to return matter to the ecosystem.

• The deer because they are consumers and break down the matter from producers to return to the ecosystem.

• The berries and flowers because they are producers and are broken down for multiple consumers in the ecosystem.
