Autotrophic –  Auto – self; troph – nutrition. The mode of nutrition in which organisms prepare their own food from inorganic raw materials. These organisms are independent of external organic sources and are called as autotrophs. Eg: green plants

Heterotrophic – The mode of nutrition in which organisms derive their food from other living organisms. It is of different types:

Saprotrophic nutrition: The mode of nutrition in which organisms obtain food from the dead and decaying organic matter by releasing digestive juices on them. Eg. Fungi, yeast and bacteria.

Parasitic Nutrition: In this mode of nutrition organisms depend on the food that is synthesised by other organisms. Organism that depends on another organism is called ‘parasite’ and organism that provides food for parasite is called ‘host’. Eg.Ticks, lice, leeches, fungi, bacteria, few plants like cuscuta.

Holozoic Nutrition: The mode of nutrition in which complex food is taken in the solid form and then digested and absorbed into the cells. Eg. Amoeba, Frog, Human beings.
