How are combustion,
respiration, and decomposition similar to each
other?

Combustion, respiration and decomposition are similar to each other because they release carbon dioxide.

Combustion is the reaction that occurs between an oxidizable material and oxygen, which is revealed through flames and generates the release of energy.

The different components that are completely oxidized, gives rise to the formation of liquid water and carbon dioxide and even sulfur dioxide.

Respiration is a gas exchange system with the environment, where a fuel molecule, glucose, is oxidized.

Humans take in oxygen through inspiration and exhale carbon dioxide as a waste product produced by the body.

The decomposition of organic matter is useful for microorganisms for two reasons: as an energy supply for their growth, and as a carbon source for the formation of new cellular material.

Carbon dioxide, methane, organic acids, and alcohols are waste products released in the acquisition of energy.

Therefore, we can conclude that combustion, respiration and decomposition are similar to each other because they release carbon dioxide.

The waste products of carbon dioxide and water are also formed. Combustion, which is the burning of carbon compounds, which are fossil fuels, is often compared to cellular respiration because the two processes are extremely similar. ... It's as if our bodies burn our food for energy.
