Question : Decomposers like fungi and bacteria are : (i) autotrophs (ii) heterotrophs (iii) saprotrophs (iv) chemo-autotrophs Choose the correct answer :

Answer»

i and iii 
i and iv 
ii and iii
i and ii 

Solution :AUTOTROPHS are chemical synthesis autotrophs and photosynthetic autotrophs which can make their own FOOD, e.g., plants.
When living organisms get their food from autotrophs or plants, they are known as heterotrophs. Heterotrophs can be PLANT eaters, carnivores and omnivores.
Saprotrophs they get their nutrition from dead organic matter or both live in plants and animals. They are called as DECOMPOSERS because they decompose dead organic matter and play an important role in cycling of mineralization.
