The two major modes of nutrition are: 1. Autotrophic Nutrition: Organisms produce their own food from inorganic substances (e.g., plants using photosynthesis). 2. Heterotrophic Nutrition: Organisms obtain food by consuming other organisms (e.g., animals eating plants or other animals).

FAQs & Answers

  1. What is autotrophic nutrition? Autotrophic nutrition is a mode of nutrition in which organisms produce their own food from inorganic substances, typically through photosynthesis, like plants.
  2. What is heterotrophic nutrition? Heterotrophic nutrition is a mode where organisms obtain food by consuming other organisms, such as animals eating plants or other animals.
  3. How do autotrophic and heterotrophic nutrition differ? Autotrophic organisms make their own food from inorganic substances, while heterotrophic organisms depend on other organisms for food.
