Question

which gas is produced by decaying animal and plant matter​

Answer 1

Answer:

Animals, during respiration, take in oxygen and release carbon dioxide gas. Plants, on the other hand, utilize this carbon dioxide gas in the process of photosynthesis to produce food and release oxygen in the atmosphere. Thus, we can say that plants and animals help each other in exchange of gases in the atmosphere.
