Nutrition in Plants and Animals – Life Processes Class 10 Notes
Nutrition: The process by which an organism takes food and utilizes it, is called nutrition.
Need for Nutrition: Organisms need the energy to perform various activities. The energy is supplied by the nutrients. Organisms need various raw materials for growth and repair. These raw materials are provided by nutrients.
Nutrients: Materials which provide nutrition to organisms are called nutrients. Carbohydrates, proteins and fats are the main nutrients and are called macronutrients. Minerals and vitamins are required in small amounts and hence are called micronutrients.
Modes of Nutrition
1. Autotrophic Nutrition.
2. Heterotrophic Nutrition
