Without Photosynthesis, Most Animal Life on the Earth Could Not

Question

Without photosynthesis, most animal life on the Earth could not survive.

Accepted Answer

This is because photosynthesis is responsible for producing oxygen, which is essential for animals to breathe. Additionally, photosynthetic plants and algae are the base of many food webs, providing energy and nutrients for herbivores, which in turn are eaten by carnivores. Without photosynthesis, the entire ecosystem would collapse.
