Study Notes
- Nutrition is the process by which living organisms obtain or make food.
Autotrophic Nutrition
- Autotrophs produce their own food from inorganic substances.
- Two main types of autotrophic nutrition are:
- Photosynthesis:
- Uses sunlight as an energy source.
- Converts carbon dioxide and water into glucose (sugar) and oxygen.
- Occurs in plants, algae, and some bacteria.
- The process involves a series of complex chemical reactions within chloroplasts.
- Chemosynthesis:
- Uses chemical energy from inorganic molecules as an energy source for creating their food.
- Different from photosynthesis in that it doesn't rely on sunlight.
- Some archaea and bacteria use chemosynthesis to produce food and energy.
- Examples include the oxidation of hydrogen sulfide to produce energy.
- Photosynthesis:
