Answer: All of the choices are correct (E). Decomposers are consumers, saprotrophs and heterotrophs. Bacteria and fungi are examples of decomposers.
Step-by-step explanation:
Decomposers are organisms that break down dead or decaying organisms. They are also grouped as consumers, saprotrophs and heterotrophs.
Saprotrophs are any organism, especially a fungus or bacterium, that lives and feeds on dead organic matter.
Heterotrophs are organisms that cannot manufacture their own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are secondary and tertiary consumers.
Bacteria and fungi are examples of decomposers. Thus, all the choices are correct. Decomposers are consumers, saprotrophs and heterotrophs while bacteria and fungi are examples of decomposers.
