False. It also occurs in plants.

Google "plant respiration" for details.

False. Respiration is the process of inhaling oxygen and exhaling carbon dioxide. While animals do undergo respiration, they are not the only ones. Plants, fungi, and even certain microorganisms also undergo respiration. Respiration in plants, called plant respiration, occurs mainly through tiny pores on the leaves called stomata. These stomata allow plants to exchange gases with the atmosphere, absorbing carbon dioxide and releasing oxygen. Additionally, many microorganisms, such as bacteria and fungi, undergo respiration to generate energy for their metabolic activities.
