Question

The food chain in which microbes split energy rich compounds of the producer community is

• A. Parasitic food chain
• B. Detritus food chain
• C. Predators food chain
• D. Producer food chain

Answer 1

The correct option is B Detritus food chain

Food chain is the sequence of populations or organisms through which food and its contained energy pass in an ecosystem with members at one step becoming food of later step of the sequence.

Common food chains are predator or grazing food chain, detritus food chain.

The detritus food chain (DFC) begins with dead organic matter. It is made up of decomposers, which are heterotrophic organisms, mainly fungi and bacteria. They meet their energy and nutrient requirements by degrading dead organic matter or detritus. These are also known as saprotrophs (sapro: to decompose).

Decomposers secrete digestive enzymes, that breakdown dead and waste materials into simple, inorganic materials, which are subsequently absorbed by them.
