What is the difference between producers and consumers in an ecosystem?

• A. Producers make their own food via photosynthesis; consumers eat other organisms.
• B. Producers are the only organisms that decompose waste.
• C. Consumers make their own food via photosynthesis.
• D. Producers depend on consumers for energy.

Answer: (A)

Think about how energy moves through an ecosystem. Producers capture energy from the sun and synthesize their own organic matter through photosynthesis, forming the energy base of the food web. Consumers obtain energy by eating producers or other organisms, so they rely on the producers for the energy that fuels life. This distinction is why the statement that producers make their own food via photosynthesis while consumers eat other organisms is the best description. The other ideas mix up roles: decomposition is done by decomposers, not producers, and producers do not depend on consumers for energy—the energy flow starts with the sun, moves to producers, and then to consumers, with energy gradually lost as heat.
