Question

which describes one of oxygens roles in earths atmosphere? allows fuels to burn forms clouds that produce rain is the gas that animals exhale is used by plants to produce food

Explanation:

Oxygen is a highly reactive gas. In combustion (burning of fuels), oxygen acts as an oxidizing agent. For example, in the reaction \(C + O_2
ightarrow CO_2\) (burning of carbon), oxygen is essential. Clouds are formed mainly due to water - vapor condensation (not oxygen). Animals exhale carbon dioxide (\(CO_2\)) not oxygen. Plants use carbon dioxide (\(CO_2\)) to produce food (glucose) via photosynthesis (\(6CO_2+6H_2O
ightarrow C_6H_{12}O_6 + 6O_2\)).

Answer:

allows fuels to burn
