The correct response to how plants and animals rearrange atoms in chemical reactions to support their functions is:
"Animals produce carbon dioxide and plants produce oxygen as an output of cellular respiration."
In this context, cellular respiration is a process where animals and plants convert glucose and oxygen into energy, carbon dioxide, and water. Animals primarily utilize this process to generate energy, while plants also perform photosynthesis to convert carbon dioxide and sunlight into glucose and oxygen, thus creating a cycle of oxygen production and carbon dioxide consumption.
