What is the energy source that allows photosynthesis to occur?
Pie

Answer:

\boxed {\boxed {\sf The \ sun }}

Explanation:

Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".

This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.

This process occurs because of the <u>sun</u>. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.
