Photosynthesis: Overview of Photosynthesis

Photosynthesis is a crucial process for life on Earth, involving complex chemical reactions in plants that convert sunlight, carbon dioxide, and water into glucose and oxygen. This process supports life by providing food and oxygen, and is summarized by a chemical equation showing the transformation of these inputs into essential outputs.

Why is photosynthesis crucial for most life forms on Earth?

• It produces nitrogen.

• It creates carbon dioxide.
