What are examples of autotrophic nutrition?

Examples explained

• Green plants: Use sunlight, CO₂, and water to make glucose by photosynthesis.
• Algae: Microscopic autotrophs in water bodies that produce oxygen and food.
• Cyanobacteria: Also called blue-green algae; carry out photosynthesis.
• Chemoautotrophic bacteria: Use chemical reactions (like oxidizing ammonia or sulfur) to get energy instead of sunlight.

Types of autotrophs

• Photoautotrophs: Use sunlight (e.g., plants, algae).
• Chemolithoautotrophs: Use inorganic compounds (e.g., sulfur bacteria, nitrifying bacteria).
