Question

how does carbon dioxide get back into the atmosphere? it is released by plants through the process of photosynthesis. it is released by plants and animals through the process of cellular respiration. it is released by solid waste excreted by animals. rewatch submit

Explanation:

• Photosynthesis: Plants take in \(CO_2\) and release \(O_2\). So the first option is wrong.
• Cellular respiration: The formula is \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+\text{energy}\). Both plants and animals perform this process, releasing \(CO_2\) into the atmosphere.

• Solid waste: Animal solid waste (feces) mainly contains undigested matter and doesn't directly release \(CO_2\) back to the atmosphere in a significant way relevant to this question.

Answer:

It is released by plants and animals through the process of cellular respiration.
