उत्तर
Photosynthesis is considered to be the most important process in the biosphere due to the following reasons:
- Photosynthesis is the biochemical process through which all plants (primary producers) produce food.
- It is responsible for the release of oxygen into the atmosphere.
- Heterotrophs are directly or indirectly dependent on autotrophs for energy and other related resources.
Therefore, photosynthesis is considered the most important process in the biosphere.
