Give reason for the following
All life on Earth is supported by Photosynthesis.

Text Solution

Verified by Experts

Our food chain starts with producers i.e. green plants as they are the only organisms which can prepare their own food by photosynthesis process. All other living organisms depend upon them directly or indirectly for food. Photosynthesis is thus the process by which oxygen is released to our atmosphere which is a life supporting gas. So we can say that directly or indirectly all life on Earth is supported by photosynthesis.
