Question 3 • Physical Science

Which processes result in the release of carbon? Choose three correct answers.

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

Explanation

Decomposers break down the remains of both consumers and producers, releasing carbon as they respire and return it to the environment. Animals also release carbon when they break down food molecules during cellular respiration. Producers taking in carbon dioxide removes carbon from the air, while making sugars and starches stores carbon in their tissues.
