Answer;
D complex carbohydrate
Explanation;
-Cellular processes produce energy which may be stored for future use when need arises. This energy is stored in complex carbohydrates such as glycogen and starch.
-These complex carbohydrates often supply energy and other nutrients and fiber needed by an organisms when need arises. Starch is the storage carbohydrate in plants while glycogen is the energy reserve in animals. When the body needs energy, the stored glycogen is readily broken down to glucose which is used to generate energy in the usable form of ATP
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. Oxygenic functions as a counterbalance to respiration; it takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere.
