Which statement about producers is false?

Which statement about producers is false?

• A. Producers convert energy from the sun into chemical energy
• B. Producers are always consumers in the food web
• C. Producers form the base of the food chain
• D. Producers perform photosynthesis in chloroplasts

Answer: (B)

Producers are autotrophs that capture energy from the sun and convert it into chemical energy stored in sugars. This energy conversion is the foundation of most ecosystems, because it provides the energy source that all other organisms rely on as it moves through the food web. Plants and many algae perform this process in chloroplasts, which house the chlorophyll pigments that capture light during photosynthesis. In some cases, producers are bacteria that obtain energy by chemosynthesis instead of photosynthesis, but they still create their own energy rather than obtaining it by eating other organisms. The statement that producers are always consumers conflicts with this autotrophic nature, so it is the false one. The other points correctly describe producers’ energy conversion, their base-of-the-food-chain role, and their photosynthetic function in chloroplasts.
