Unit 1 Test Review (Module C)

Which statement describes the flow of matter and energy in decomposers?

• A decomposer digests living organisms to produce energy, water, and carbon dioxide.

• A decomposer uses carbon dioxide, water, and energy from the sun to produce oxygen and sugars.

• A decomposer consumes dead or dying organisms to produce oxygen and sugars.

• A decomposer breaks down decaying matter to produce energy and release nutrients back into the environment.
