Q. The “Bacteria & Fungi” are known as?

[A] Autotrophs

[B] Saprotrophs

[C] Carnivores

[D] Herbivores

Answer: B
Notes:

Explanation: 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.
