Photosynthesis is important to animals because oxygen, which animals breathe, is released as a byproduct; carbon dioxide, which animals need for cellular respiration, is released as a byproduct; it prevents any of the sun's energy from being absorbed by animals' skin; it prevents carbon dioxide from destroying animals' habitats.
