The producers capture energy from sunlight. The food web is found in a terrestrial ecosystem. The producers in the web are single-celled organisms. The food web contains many herbivores and omnivores.
I gave my students this multiple choice question: A student is shown a slide of cells from a species of producer in a food web. The student observes that the cells have chloroplasts. What conclusion about the food web is best supported by these findings?

Only one answer is correct among these 4 choices:
- The producers capture energy from sunlight.
- The food web is found in a terrestrial ecosystem.
- The producers in the web are single-celled organisms.
- The food web contains many herbivores and omnivores.

Could you tell me which one is correct?

The producers capture energy from sunlight.
