    Study Notes

    Types of Nutrition

    • Organisms are classified based on their nutritional methods: autotrophic and heterotrophic nutrition.

    Autotrophic Nutrition

    • Autotrophic organisms synthesize their own food using simple inorganic substances.
    • Key components include water, mineral salts, and carbon dioxide.
    • Photosynthesis is a common example, requiring sunlight for energy conversion.
    • "Autotrophic" derives from Greek terms: "auto" (self) and "trophic" (nutrition), indicating self-sufficiency in food production.

    Heterotrophic Nutrition

    • Heterotrophic organisms rely on other organisms for nutrition, meaning they cannot produce their own food.
    • This group includes animals, fungi, and most bacteria, which consume organic materials.
    • Heterotrophs are essential for nutrient cycling in ecosystems, breaking down complex organic matter.
