Solution
The correct option is D Microorganisms Of all the organisms in an ecosystem the most important role is played by decomposers. Decomposers release back to the environment nutrients, which are trapped in dead and decaying organic matter.
Decomposers derive energy and nutrition from dead and decaying matter and hence, act as "nature's scavengers". If the nutrients are not released back to the environment, slowly all the mineral nutrients will become trapped in dead bodies of plants and animals and body wastes of organisms and biogeochemical cycles of mineral nutrients will ultimately stop.
