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 11 of 11
