Meaning, definitions, types of nutrition in Hindi

Hello friends, today in this article we are going to know. What is nutrition meaning in Hindi, what is the meaning of nutrition in Hindi, what is the types of nutrition meaning in Hindi. Friends, by the end of the article you will get a lot of information related to nutrition.

पोषण का मतलब(What is the meaning of Nutrition)

Organisms require energy for the operation of biological processes, growth, prevention of wear and tear etc. In order to get energy, food items are needed which are obtained by the organism through the process of nutrition. Organisms have different types of nutrition methods according to their needs and environment. The simplification of complex foods obtained by nutrition takes place through oxidation and reduction reactions in various steps. This process is called respiration. Oxygen is used in this and energy is released. In a broad sense, respiration is the sum total of all those activities by which energy is produced in the body.

Types of Nutrition

Two major requirements of each organism for the smooth running of life processes

(i) Continuous supply of energy for carrying out the metabolic activities of life,

(ii) Production of protoplasm for growth of the body and repair of damaged tissues.

To fulfill these needs and to maintain the existence of its life, every living being needs food throughout life. Various elements present in the food perform these functions. Such elements of food are called nutrients. Therefore, the method by which organisms take in and use the nutrients is called nutrition.

methods of nutrition

Nutrition in living beings takes place mainly by two methods-

(i) स्वपोषण (Autotrophic nutrition)
(ii) परपोषण (Heterotrophic nutrition)

1) स्वपोषण (Autotrophic nutrition)-

The word autotroph is derived from the combination of two Greek words, auto and troph. The word auto means ‘self’ or ‘self’ (auto = self) and troph means ‘troph nutrition’. Therefore, organisms that synthesize their own food without relying on other organisms for food are called autotrophs or autotrophs.

All green plants are autotrophs. A type of structure found in these plants is called chloroplast. A green pigment called chlorophyll is found in chloroplasts. Due to the presence of chlorophyll, the color of the plants appears green. Such green plants synthesize their food carbohydrates (organic matter) by getting energy from sunlight, carbon dioxide (CO2) and water (H2O) in the presence of chlorophyll. This process is called photosynthesis.

2) परपोषण (Heterotrophic nutrition)-

Due to the absence of chlorophyll, all animals and fungi are not able to synthesize their own food like plants. Therefore, they are completely dependent on other organisms for food. Organisms that depend on other organisms for their food in one way or the other are called heterotrophs.

The word heterotroph is derived from the combination of two Greek words, hetero and troph. The word hetero means ‘odd’, ‘different’ or ‘on’ (hetero = different or other) and the word troph means ‘nutrition’. Thus, aliquot is the process in which organisms do not synthesize their own food, but obtain their food in one form or the other from other sources.

The basic difference between autotrophy and overnutrition is that in autotrophy, organisms synthesize complex organic molecules from simple inorganic molecules, but in parenting, the complex organic molecules absorbed by animals are reduced by various biological processes into simpler organic molecules (degradation of breakdown). it happens.

Types of nutrition

There are mainly three types of nutrition.

1) Saprophytic nutrition

The Greek word sapros means absorption (sapros = to absorb). Thus, in this type of nutrition, organisms absorb their food from the body of dead animals and plants, from the surface of their body, in the form of dissolved organic matter.

Organisms that obtain their food through satiating nutrition are called saprophytes. In many fungi, bacteria and some protozoa, nutrition occurs by this method. Dead organisms take their food mainly in the liquid state through absorption.

Survival nutrition is of great importance in nature. After the death of animals and plants, their dead bodies decompose, that is, by decomposing, they convert them into their original elements. Such basic elements are again replaced in the soil and the gas generated gets mixed in the atmosphere. These elements are again taken up by green plants from the soil and used. This cycle goes on continuously in nature.
lives. For this reason, the dead are also called decomposers.

2) Parasitic nutrition-

Parasite is a combination of two Greek words, mercury and cytos. Para means ‘near’, ‘beside’ or ‘side’ (para = beside) and sitos means ‘nutrition’.

In this type of nutrition, living beings get their food from other living beings, either permanently or temporarily, in contact with them. The food of such organisms is the organic matter present in the body of other living beings. Thus, the organisms that feed are called parasites and the organism from whose body the parasite obtains its food is called host. Parasitic nutrition. Many types of fungi, bacteria, some plants, such as dander and many animals; For example, found in roundworm, hookworm, tapeworm, Entamoeba histolytica, malaria parasite etc.

Not all parasites have homogeneity in their diet. The organic matter consumed by parasites as food is usually in liquid form.

3) Holozoic nutrition-

The word Holozoic is a combination of two Greek words, holo and joik. The word holo means ‘completely’ (holo = complete) and zoic means ‘animal-like’ (zoic = animal-like). That is, the nutrition in which animals take their food in the form of solid or liquid by the method of taking food of animals, is called holozoic nutrition. Those organisms which are fed by this method are called zoonotic. This type of nutrition is generally characteristic of animals and is found in amoeba, frog, human etc.

ways of obtaining nutrition in organisms

Different types of nutrients are needed in organisms according to their needs, the ways of obtaining them are also different in organisms. In unicellular organisms, food is taken up from the entire surface of the cell, whereas in multicellular and complex organisms, there are special organs for this.
