The molecule(s) in the atmosphere that comes from animals is -

• a. Carbon dioxide, CO2
• c. Methane, CH4

Humans and other animals contribute to the atmospheric gas cycle such as nitrogen gas, oxygen gas, carbon dioxide, and other gases. Animals give up mainly two gases in the atmosphere that are:

• Carbon dioxide: during cellular respiration, animals release carbon dioxide as a waste product with energy. This carbon dioxide is removed from the body of animals to the atmosphere.
• Methane is a gas that is also released by the animals to the atmosphere but in very low concentration or quantity. During the digestion process, methane gas is formed in the digestion tract. methane will be released as burp mainly.

Thus, the molecule(s) in the atmosphere that comes from animals is -
