What the differences between autotrophic nutrition and heterotrphic nutrition ?

Explanation

Autotrophic Nutrition :
(a) In this mode of nutrition, the organism prepare their own food from inorganic raw materials.
(b) This form of nutrition is mainly of two types.
(i) Phototrophic (in which energy is obtained from sunlight) which can be seen in green plants.
(ii) Chemoautrotrophic (in which energy is obtained by the oxidation of chemicals which can be seen in few types of bacteria such as sulphur bacteria)
Heterotrophic Nutrition
(a) In this mode of organisms get their food prepared by autotrophs or from other organic resources.
(b) The different forms of heterotrophic nutrition in cludes :
(i) Saprophytic (feeding on dead and decaying matter)
(ii) Parasitic (obtaining nutrition from other without killing)
(iii) Holozoic (obtaining solid food through ingestion, digestion, absorption, assimilation and egestion).
(iv) Predation (obtaining nutrition by killing others)
