Decomposers like fungi and bacteria are:

i. autotrophs

ii. heterotrophs

iii. saprotrophs

iv. chemo-autotrophs.

Choose the correct answer:

The decomposers like fungi and bacteria are heterotrophs i.e., they are not able to prepare their own food and they are saprotrophs as it depends on dead and decaying material. They are not autotrophs as they can not make their own food like plants and they are also not chemo-autotrophs as they cannot use inorganic energy sources to synthesize food from carbon dioxide.

Thus, decomposers like fungi and bacteria are heterotrophs and saprotrophs.
