Final answer:
The two major products of photosynthesis are glucose, which is a sugar that serves as an energy source for plants, and oxygen, which is a byproduct essential for animal respiration.
Step-by-step explanation:
The two major products of photosynthesis are glucose and oxygen. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose. This glucose serves as a vital source of energy for the plant and can also be converted into other carbohydrates like starch for storage. Oxygen is released as a byproduct during this process. It's important for maintaining life on Earth as it is utilized in the respiratory processes of animals and other non-photosynthetic organisms.
