Why do herbivores need oxygen?

Herbivores need oxygen for cellular respiration, a process that converts food into energy. Although they primarily consume plant material, which is rich in carbohydrates, they require oxygen to break down these carbohydrates efficiently to produce ATP, the energy currency of cells. This energy is essential for their growth, movement, and various bodily functions. Additionally, oxygen helps in the metabolism of nutrients absorbed from their plant-based diet.
