Decomposers like fungi and bacteria are
(i) autotrophs (ii) heterotrophs
(iii) saprotrophs (iv) chemo-autotrophs
Choose the correct answer
1. (i) and (iii)
2. (i) and (iv)
3. (ii) and (iii)
4. (i) and (ii)
Ans. (c) Autotrophs (Chemoautotrophs and photoautotrophs) are those organisms that are able to synthesize their own food. e.g.. plants while the organisms which derive their food, (from autotrophs or plants) are termed as heterotrophs. Heterotrophs may be herbivores, carnivores, and omnivores.
Saprotrophs are the organisms which obtain their nourishment from dead organic matter or remains of both plant and animals. They are also known as decomposer as they play an important role in the recycling of minerals by decomposing dead organic matter
