difference b/w photosynthesis and chemosynthesis.
Photosynthesis | Chemosynthesis |
Photosynthesis is the process by which green plants synthesize their own food using carbon dioxide and water in presence of sunlight and chlorophyll. | The process of carbohydrate synthesis, in which the organism uses chemical reactions to obtain energy from inorganic compounds, is called chemosynthesis. |
Photosynthesis is powered by sunlight | Chemosynthesis runs on chemical energy. |
In photosynthesis water is needed to fuel the process. | In chemosynthesis water is an end result of the process. |
Photosynthesis occurs in plants and some bacteria. | Chemosynthesis occurs at the heart of deep-sea communities, sustaining life in absolute darkness, where sunlight does not penetrate. |
Photosynthesis is a process that can take place in either a terrestrial or aquatic setting | Chemosynthesis occurs in dark. |
