Nutrition is an essential part of life for all living organisms. In Class VI, students learn about the importance of food and the components that make up a balanced diet. Carbohydrates, proteins, fats, vitamins, and minerals are all necessary for the body to function properly. These components of food are known as nutrients.
Organisms can obtain their nutrients from dead and decaying matter through a process called saprotrophic nutrition. Heterotrophic nutrition is when organisms take food from green plants or animals. There are also some plants that can trap insects and digest them for nutrition. Organisms can be classified into two main types based on their mode of nutrition: autotrophs and heterotrophs.
Autotrophic nutrition is when organisms produce their own food from a simple substance, such as carbon dioxide and water. Heterotrophic nutrition is when organisms rely on other organisms for their food source. In CBSE Class 7 Science, students learn about nutrition in plants. This includes understanding the different modes of nutrition in plants, such as autotrophic and heterotrophic nutrition.
Students also learn about insectivorous plants and saprotrophic plants. The free download of the CBSE Class 7 Science Notes Chapter 1 Nutrition in Plants PDF is part of the Class 7 Scientific Notes for a quick review. Understanding the different modes of nutrition in plants is important for students to understand how plants obtain their nutrients and energy. It also helps them to understand how different organisms interact with each other in an ecosystem. With this knowledge, students can better appreciate the importance of maintaining a balanced diet and how it affects their overall health.
