- AAll consumer will die
- BEnergy cycle will be inverted
- CBalance of biogeochemical cycle will be disturbed
- DOnly herbivores will die
Explanation:
Decomposers are saprotrophs, which decompose the organic remains by secreting extracellular digestive enzymes.
Due to degradation of organic remains, decomposers are also called as reducers. They are also known as mineralisers as they release minerals trapped in organic remains.
Detrivores are decomposers as well as scavengers, e.g., earthworm.
Decomposition of organic wastes and dead and decaying plants and animals returns the minerals locked in living systems back to the environment.
