Which process results in the release of carbon

- 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.

Explanation:

Animal breaks down food by doing cellular respiration that will produce CO2 that released into the atmosphere. The process of break down by decomposer should be similar. 

Producer or plants will take CO2 to do photosynthesize and makes sugar, not releasing it.
