Decomposers like fungi and bacteria are:
i. autotrophs
ii. heterotrophs
iii. saprotrophs
iv. chemo-autotrophs.
Choose the correct answer:
(a) i and iii, (b) i and iv (c) ii and iii, (d) i and ii
The answer is the option (c) (ii) and (iii)
Explanation: Decomposers depend on other organisms for food. Hence, they are heterotrophs. They obtain nutrients by decomposing the detritus and hence are called saprotrophs.
