Types of Nutrition in Organisms

The video explains the two main modes of nutrition: autotrophic and heterotrophic. Autotrophic organisms, like plants, produce their own food through photosynthesis or chemosynthesis. Heterotrophic organisms, including animals and fungi, depend on others for food. The video further classifies heterotrophic nutrition into saprophytic, parasitic, and holozoic types, providing examples and explanations for each.
