Question

What is nutrition?What type of nutrition is seen in green plants and the majority of animals?

Answer 1

Nutrition, more specifically nutritional science, is a science that studies the physiological process of nutrition, the interpretation of nutrients and other substances in food in relation to the maintenance, growth, reproduction, health and disease of the organism.

Complete answer:
Food components are necessary for our body and are called nutrients.
The mode of nutrition in which organisms themselves make food from simple substances is called autotrophic nutrients.
Animals and most other organisms consume ready-made food prepared by plants and are called heterotrophic nutrients.

The leaves are of a green pigment called chlorophyll. It helps to capture the energy of the sunlight. Nutrition is a process of obtaining energy in the form of food that is necessary for body growth and metabolism. Each and every organism obtains its nutrition by different means. Plants exhibit an autotrophic mode of nutrition.

They're preparing their own food. They are able to fix carbon dioxide by using sunlight energy. In the food chain, they are the primary producers. The majority of animals are heterotrophs. They can't prepare their own food. They depend on other organisms for their nutrition, such as plants or other animals. They are consumers of the food chain.

Various types of heterotrophic plants are listed below, which are mainly classified according to their mode of nutrition:
1)Parasitic
2)Insectivorous
3)Saprophytic
4)Symbiotic:

Some heterotrophic plants depend on other plants and animals for nutritional purposes. These plants are known as parasitic plants. The host is not, however, benefited from the parasite.

Some plants have special structural features that help them trap insects and are commonly referred to as carnivorous or heterotrophic plants.These plants digest the insects by secreting the digestive juices and absorbing the nutrients from them. These plants are growing on the soil that lacks minerals.

Saprophytic plants derive their nutrition from dead and decaying plants and animals. They dissolve dead and decaying matter by secreting digestive juices and by absorbing nutrients.

When two different plants belonging to two different categories have a close association, they are called symbiotic. In this, both plants are benefited from each other.

Note: Plants require two types of nutrients: macronutrients and micronutrients. Macronutrients include nitrogen, phosphorus, potassium, calcium, magnesium and sulphur.Boron, chlorine, copper, iron, manganese, molybdenum, and zinc are micronutrients.Plants absorb nutrients from their roots. They transport nutrients and water through the stem to parts above ground level.
