|
|
To make food (glucose) for themselves. As a byproduct they make oxygen as well.
|
|
|
To make ATP (cell energy). Carbon dioxide and water are also produced as byproducts.
|
|
|
To make oxygen, carbon dioxide, and glucose for themselves.
|
|
|
To make carbon dioxide and water that animas use.

Detailed explanation-1: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels. Without this process, life on Earth as we know it would not be possible.
Detailed explanation-2: -Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
Detailed explanation-3: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.
Detailed explanation-4: -The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
Detailed explanation-5: -It ensures that all living species have access to oxygen in the atmosphere. It keeps the ecosystem’s oxygen and carbon dioxide levels in check. Plants are the source of fossil fuels. Energy is locked in fuel as a result of photosynthesis in the sun.
