Text solution
Verified
- The autotrophic organisms are self-feeders that can synthesize the organic compounds using carbon dioxide as a source of carbon and water as an electron donor. Green plants are photoautotrophs that carry out photosynthesis, a process that requires atmospheric carbon dioxide, water, sunlight, and chlorophyll.
- The energy of sunlight is trapped by chlorophyll and is used to fix carbon dioxide into organic compounds (glucose) in the presence of water. These organic compounds are used by plants for their own growth and maintenance and stored in the form of starch that serves as a source of energy when required. Since water molecules serve as an electron donor, oxygen is produced during the process of photosynthesis as a by-product and is released into the air.
