Dear friends, welcome to our channel. Now we will know about nutrition and types of nutrition. Good nutrition is an important part of a leading a healthy lifestyle. The process of taking in food and using it for growth repair is called nutrition. A large variety of substances are taken as a food from a single cell or organism like amoeba to the complex multi-cell or organism like the human body. The mode of acquiring food also varies from cell to cell and organism to organism. Nutrition. It is directly classified into two types. One is autotropic nutrition and the other one is the heterotropic nutrition. Heterotropic nutrition further classified into four types. First one is the holozyc nutrition. Second one is the saprophytic nutrition. Third one is the parasitic nutrition and fourth one is the mixotropic nutrition. Autotropus An organism capable of synthesizing its own food from inorganic substances using light or chemical energy. Green plants all get uncertain bacteria are autotropus. One helmet and other scientists believe that plants get their food material not only from the soil but also from other sources. The process of photosynthesis makes plants the universal food providers for all living organisms. Heterotropic nutrition is a type of a nutrition in which organisms depend upon other organisms for food to survive. Heterotropic organisms have to take in all the organic substances they needed to survive. All animals, fungi and non-photosynthesizing plants are heterotropes. Types of heterotropic nutrition Previously we know that heterotropic nutrition is classified into four types. One is the holozyc nutrition. Second one is the saprophytic nutrition. Third one is the parasitic nutrition. Fourth one is the mixotropic nutrition. Let us see one by one. Holozyc nutrition In holozyc nutrition, the digestion of food follows after the ingestion of food. Thus digestion takes place inside the body of the organism. Holozyc nutrition happens in five steps that is ingestion, digestion, absorption, assimilation and ejection. Amibha takes in-foot using temporary finger-like extensions that is called pseudo-podia of the cell surface. In paramesh, food is moved to the spot by the moment of celia which covers the entire surface of cell wall where the food is ingested that is called cyto-storm. Saprophytic nutrition The mode of a nutrition in which an organism obtains nutrients from dead and decaying organic matter is called saprophytic nutrition. Examples, rhizopus, it is called bread mold, mu car. It is also called as a pin mold yeast. Agaricus, it is also called as mushrooms. Parasitic nutrition Parasitic nutrition is a mode of a heterotropic nutrition where an organism lives on the body surface or inside of the body of another type of organism. The parasite obtains nutrition directly from the body of the host. The parasites derive their nourishment from their host. For example, daughter plant also known as cascuta. Daughter, genus cascuta, nearly 170 species are there. Daughter is a leafless, thinning parasitic plant, belong to the morning glow to family, is also known as a convoy-villacy. The daughter contains a less amount of chlorophyll. cascuta reflexa has been found to have a very small amount of chlorophyll. The daughter's seed germinates forming an anchoring root and then seeds up a slender stem that grows in a spiral fashion until it reaches a host plant and forms a story. Water is drawn through the story from the host plant's zylam and nutrients are drawn from its foam. Mixerotropic nutrition Mixerotropic nutrition refers to organism which are both autotrophes and heterotrophes. A mixerotroph is an organism that can use a mix of different sources of energy and carbon instead of having a single trophic mode on the continuum from complete autotrophy at one end to heterotrophy at another.
