Ecology and the Environment

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.

Which of these are the materials needed in order for this organelle to perform the process of photosynthesis?

• sunlight + water + oxygen

• sugar + sunlight + oxygen

• light energy + water + carbon dioxide

• chemical energy + sugar + water
