Answer :
Photosynthesis uses light as energy source, and cell respiration uses chemical energy.
Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy
Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.
Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.
