Why is photosynthesis vital for life?
a. photosynthesis maintain atmospheric levels of oxygen and carbon dioxide.
b. photosynthesis is a direct means of energy production for many organisms.
c. photosynthesis is an indirect means of energy production for many organisms.
d. all of the above

The correct answer would be d. All of the above

Photosynthesis is the process by which plants convert solar energy into the chemical energy or food.

Photosynthetic organisms are called autotrophs which are present at the first trophic level in any food chain.

Thus, all other organisms whether herbivores or carnivores depend on plants directly or indirectly for their energy needs.

In addition, plants with the help of photosynthesis maintain atmospheric levels of oxygen and carbon dioxide. They remove carbon dioxide from the air and release oxygen into it.
