Green plants and certain bacteria manufacture their own food. Which one of the following nutrition process do they adopt?

Correct option is C

Correct Answer: (c) Autotrophic Nutrition

Autotrophic nutrition is the process through which green plants and certain bacteria manufacture their own food using sunlight, water, and carbon dioxide. They do this through a process called photosynthesis, where chlorophyll captures light energy to produce glucose, a type of sugar, which serves as their food.

Information Booster:

• Types of Autotrophs:
  • Photoautotrophs: Use light energy (e.g., green plants, algae, cyanobacteria).
  • Chemoautotrophs: Use chemical energy (e.g., sulfur bacteria, nitrifying bacteria).
• Importance of Autotrophs: They form the base of the food chain by producing organic matter that supports all other life forms.

​Additional Knowledge:

• Holozoic Nutrition: This process is adopted by animals and humans, where food is ingested, digested, absorbed, and egested.
• Parasitic Nutrition: Some organisms, like parasitic worms or plants, obtain their nutrition from a host organism, often harming it in the process.
• Saprotrophic Nutrition: Organisms like fungi and some bacteria feed on dead organic matter by secreting digestive enzymes and absorbing the nutrients.
