B The microorganisms help keep nutrients cycling through the ecosystem.

Explanation:

Microbes form a very important part of the ecosystem. Along with other decomposers like fungi they help to recycle the nutrients.

Microbes break down dead and decaying matter, plant litter and animal waste into smaller components for their own utilization. This decomposition process is accompanied by release of chemicals like nitrogen, phosphorus and carbon in soil and atmosphere which can be again used by plants and animals. Once these animals and plants die, they again go through the same cycle. Hence microorganisms help keep nutrients cycling through the ecosystem.
