Why are animals important to the process of photosynthesis?

• Animals eat plants, which makes space for more plants to grow.

• Animals digest food, which provides the starting materials for photosynthesis.

• Animals release carbon dioxide, which provides the starting materials for photosynthesis.

• Animals produce energy in the form of heat, which is necessary for photosynthesis to occur.
