Types of nutrition

Autotrophic
Change simple organic materials into complex organic material , to use as a food source. Eg:- plants, algae and bacteria
1 of 11
Heterotrophic
Have to feed on other organisms, directly or indirectly. Eg:- animals, protoctists and bacterias
2 of 11
Photoautotrophic (autotrophic)
Uses light energy to synthesise complex organic material. Eg:- plants
3 of 11
Chemoautotrophic (autotrophic)
Uses inorganic chemicals to synthesise organic material Eg:- Bacteria (in the nitrogen cycle)
4 of 11
Symbiotic (heterotrophic)
Interaction between two species, which provide both or one with nutrition.
5 of 11
Saprotrophic (heterotrophic)
Feed on dead or decaying material by extracellular digestion. Eg:- decomposers
6 of 11
Holozoic (heterotrophic)
Ingest to digest in a specialised digestive system g:- animals
7 of 11
Mutualistic (symbiotic)
Nutrition where both organisms benefit. Eg:- lichen
8 of 11
Parasitic (symbiotic)
Feed on other living organisms and causes harm to them. Eg:- head lice
9 of 11
Endoparasitic (parasitic)
Parasite which survives inside the host (gut/intestine), absorbs pre-digested nutrients. Eg:- Pork tapeworm
10 of 11
Ectoparasitic (parasitic)
Survives outside the host. Eg:- head lice
