Detailed explanation-1: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Detailed explanation-2: -Plants produce sugar and oxygen in a process called photosynthesis, by using sunlight, water, and carbon dioxide. This is an important process on Earth, since it removes carbon dioxide from the air and provides food for us.

Detailed explanation-3: -During photosynthesis, leaves convert water and carbon dioxide to a kind of sugar called glucose.
