Question

Which processes result in the release of carbon? Select three options.

Animals break down food molecules to obtain energy.
The remains of producers are broken down by decomposers.
The remains of consumers are broken down by soil decomposers.
Producers take in carbon dioxide.
Producers make sugars and starches.

Answer 1

Correct answers:
- Animals break down food molecules to obtain energy.
- The remains of producers are broken down by decomposers.
- The remains of consumers are broken down by soil decomposers.

Reason: Animal respiration and decomposition of dead producers and consumers release carbon (mainly as CO2) back into the environment. The other two statements describe carbon uptake (photosynthesis), not release.
