Nutrition is a vital process for the survival of all organisms, and it is defined as the ingestion of food to carry out different functions of the body. There are two main types of nutrition: autotrophic and heterotrophic. Autotrophic nutrition is when an organism can prepare its own food, such as plants, while heterotrophic nutrition is when an organism relies on another organism for food. Depending on the complexity of the food molecules, different living beings follow different modes of nutrition. Heterotrophic nutrition is further divided into saprophytic nutrition, parasitic nutrition and holozoic nutrition.
Saprophytic nutrition is when an organism obtains its food from decaying organic matter, such as dead plants, animals, and rotten bread. Parasitic nutrition occurs when an organism obtains its nutrition from other living organisms. Lastly, holozoic nutrition is when an organism carries the body's complex food material to the body through a process of ingestion, digestion and absorption into the body's cells. In class 10, students learn about the different types of nutrition and how they are essential for the survival of organisms. They also learn about the importance of a balanced diet and how it can help maintain good health.
Additionally, students learn about the various nutrients that are required by the body and how they can be obtained from different sources. Overall, understanding the different types of nutrition is essential for class 10 students as it helps them understand how their bodies work and how to maintain a healthy lifestyle. With this knowledge, they can make informed decisions about their diet and lifestyle choices.
