What happens to the carbon when the animal dies?

When an animal dies, its body undergoes decomposition, during which microorganisms break down organic matter. This process releases carbon back into the environment in various forms, primarily as carbon dioxide (CO2) through respiration by decomposers. Some carbon may also be converted into organic compounds in the soil or remain stored in the form of fossil fuels over geological timescales. Ultimately, the carbon is recycled within the ecosystem, contributing to the carbon cycle.
