Question

Explain the types of nutrition with examples.

Answer 1

Two basic types of nutrition include autotrophic and heterotrophic. These kinds define how organisms get food and energy.

1. Autotrophic Nutrition: Autotrophic nutrition involves organisms using carbon dioxide, water, and sunlight to make their energy. These organisms are autotrophs.
   1. Examples:
      1. Plants: Photosynthesis turns sunlight, carbon dioxide, and water into glucose and oxygen in most green plants.
      2. Algae: Using photosynthesis, algae manufacture their food.
      3. Certain Bacteria: Cyanobacteria employ photosynthesis, while deep-sea hydrothermal vent bacteria use chemosynthesis.
2. Heterotrophic Nutrition: Since they cannot produce food, heterotrophic creatures depend on others. These organisms are heterotrophs.
   1. Examples:
      1. Animals: Lions, humans, and other animals eat vegetation and animals.
      2. Fungi: Mushrooms and other fungi get nourishment from decomposing organic waste.
      3. Certain Bacteria: Some bacteria eat organic molecules like parasites or decomposing dead creatures.

Both types of nutrition describe how creatures get their energy in nature.
