Nutrition is the process of obtaining energy and nutrients from food. It is essential for the growth, development, and maintenance of the body. There are two main types of nutrition: autotrophic and heterotrophic. Autotrophic nutrition is the process of obtaining energy and nutrients from simple inorganic materials, such as sunlight, carbon dioxide, and water.
Organisms that use this type of nutrition are called autotrophs. Examples include plants, algae, and bacteria (cyanobacteria).Heterotrophic nutrition is the process of obtaining energy and nutrients from complex organic materials. Organisms that use this type of nutrition are called heterotrophs. Heterotrophic nutrition can be further divided into three types: saprophytic nutrition, holozoic nutrition, and parasitic nutrition. Saprophytic nutrition is the process of obtaining energy and nutrients from decaying organic matter, such as dead plants, animals, and rotten bread.
Holozoic nutrition is the process of ingesting, digesting, absorbing, and assimilating solid and liquid material. This type of nutrition is exhibited by organisms such as amoeba. Parasitic nutrition is the process of obtaining energy and nutrients from another organism without killing it. It is important for class 10 students to understand the different types of nutrition in order to gain a better understanding of how organisms obtain energy and nutrients.
