What is photosynthesis?
Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide.
When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.
Thus, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.
