Detailed explanation-1: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-2: -Energy enters an ecosystem when producers carry out photosynthesis, capturing energy from the sun and storing it as chemical potential energy. During this process, matter from the environment (in the form of C O X 2 CO2 COX2 and H X 2 O H2O HX2O) is taken in and rearranged into organic molecules (sugars).

Detailed explanation-3: -There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

Detailed explanation-4: -Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on Earth. Photosynthesis also results in the release of oxygen into the atmosphere. In short, to eat and breathe humans depend almost entirely on the organisms that carry out photosynthesis.

Detailed explanation-5: -The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants.
