Answer Details
The processes by which animals release carbon dioxide into the air are respiration and decay.
Respiration is the process by which animals take in oxygen and release carbon dioxide as a waste product. This process occurs continuously in animals as they use oxygen to release energy from the food they consume. As a result, carbon dioxide is released into the air as a byproduct.
Decay, on the other hand, is the process by which dead organic matter breaks down and decomposes. During this process, microorganisms break down the organic matter and release carbon dioxide as a byproduct. This carbon dioxide is then released into the air.
