Question

For recycling of materials, which of the following is most necessary?

• A. Producers
• B. Consumers
• C. Decomposers
• D. None of the above

Answer 1

The correct option is C Decomposers

The biogeochemical cycle mainly involves the exchange of materials between biotic and abiotic components of the biosphere. The bio-genetic nutrients are essential elements required by organisms for their body building and metabolism which are provided by the earth and returned to earth after the death of organisms and/or through excreta of animals. The decay of excreta and dead bodies of organisms is carried out by decomposers. The activity of decomposers releases the bio-genetic nutrients from excreta and dead bodies of organisms. Hence, decomposition activity is the most important part of biogeochemical cycles. Else all the nutrients will slowly become trapped in excreta and dead bodies of organisms.

So, the correct answer is option C.
