Solution
The correct option is Cii and iii Fungi and bacteria are the decomposers which are both heterotrophic and saprotrophic biotic component in an ecosystem. They are heterotrophs as they derive its nutritional requirements from complex organic substances. These complex organic substances are obtained from dead and decaying matter hence they are also called as saprotrophs.
