role of microorganisms in ecosystem slideshare
How do microbes form the backbone of every ecological system?
Microbes form the backbone of every ecological system by controlling global biogeochemical cycling of elements essential for life. A biogeochemical cycle is a pathway by which a chemical element (such as carbon or nitrogen) circulates through and is recycled by an ecosystem.
How do microorganisms affect the ecosystem?
Microorganisms participate in a host of fundamental ecological processes including production, decomposition, and fixation. They can also have additional indirect effects on the ecosystem through symbiotic relationships with other organisms.
What role do microorganisms play in biogeochemical systems?
Microorganisms play a primary role in regulating biogeochemical systems in virtually all of our planet ‘s environments. Microbes participate in essential biogeochemical cycling events such as carbon and nitrogen fixation.
Do microorganisms regulate biogeochemical cycles?
Although biogeochemical cycles in a given ecosystem are coordinated by the full complement of living organisms and abiotic factors that make up that system, microorganisms play a primary role in regulating biogeochemical systems in virtually all of our planet’s environments.
