Answer 1

Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates.[1] It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.

Energy from sunlight, water absorbed by the roots and carbon dioxide from the atmosphere produce glucose and oxygen by photosynthesis

Photosynthesis is very important for life on Earth. Green plants build themselves using photosynthesis. Algae, protists and some bacteria also use it. Some exceptions are organisms that directly get their energy from chemical reactions; these organisms are called chemoautotrophs.
