Difference between Chemosynthesis and Photosynthesis

Chemosynthesis

1. The amount of energy available in chemosynthesis is much.
2. There is no gain of energy from outside the planet.
3. No light is involved in this process.
4. Exothermic reactions.
5. Energy required for the process is obtained by the oxidation of certain inorganic substances available in the environment

Photosynthesis

1. The amount of energy in photosynthesis is much more than in chemosynthesis.
2. There is distinct gain of energy from outside the planet.
3. There is distinct gain of energy from outside the planet.
4. It takes place in the presence of light.
5. Endothermic reactions.
6. Solar energy trapped by the pigments is used in the process.
