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.

Explanation:

• Animals break down food molecules to obtain energy: This is cellular respiration. In this process, glucose ($C_6H_{12}O_6$) reacts with oxygen ($O_2$) to produce carbon dioxide ($CO_2$), water ($H_2O$), and energy. The chemical equation is $C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+\text{Energy}$. Carbon is released as carbon dioxide.

• The remains of consumers are broken down by soil decomposers: Decomposers (like bacteria and fungi) break down the organic matter in the remains of consumers. Through decomposition, carbon - containing compounds in the remains are converted into carbon dioxide (released back to the atmosphere) and other inorganic substances.
• The remains of producers are broken down by decomposers: Similar to the breakdown of consumer remains. Producers' remains contain organic carbon compounds. Decomposers break them down, and carbon is released as carbon dioxide during the decomposition process.

Answer:

• Animals break down food molecules to obtain energy.
• The remains of consumers are broken down by soil decomposers.
• The remains of producers are broken down by decomposers.
