Which phrases describe oxygen's roles in Earth’s atmosphere? Select three options. allows fuels to burn forms clouds that produce rain is the gas that animals breathe is used by plants to produce food forms ozone that absorbs the Sun's harmful rays

Explanation:

Oxygen is a powerful oxidizer (oxidizing agent or oxidant) that burns the fossil fuel, reacts with carbon, and produce CO2/CO. Although, it is not a sole oxidizer available on Earth but 99.9% of combustion reactions takes place in the presence of oxygen. It does the job by accepting electrons very fast in its valence shell.

Animals use oxygen to breath which produces ATPs through a series of chemical reactions particularly in electron transport chain. Again, it acts as a oxidizer and accepts electron in the electron transport chain. This gradient of electron flow is necessary for ATP production. In the end, water and CO2 are produced with ATPs.

Oxygen molecules in the stratosphere reacts with solar radiation (UV) and produce oxygen atoms. Thereon, each atom reacts further with the oxygen molecule to produce ozone. Ozone layer acts as a shield and doesn't allow penetration of harmful rays to the biosphere where living organisms are present.
