What role does microbiome play in the environment and microbes regulate Earth's climate?
Microbes play an important role in climate because they release carbon dioxide into the atmosphere when they eat. Bacteria and their main predators, protists, account for more than 40 times the biomass of all animals on Earth. As a result, they have a huge effect on carbon dioxide emissions. Oceans, soils and rivers all host microbiome communities that impact entire ecosystems. A healthy soil microbiome is crucial for the growth of crops and wildlifeand water microbiomes in oceans and rivers help feed and support a vast range of species. This combination of microbiomes upholds the fabric of life. As part of these biogeochemical cycles, microbes both produce and consume heat-trapping gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Over Earth's history, the climate has changed in response to changes in the abundance of greenhouse gases in the atmosphere.

These organisms are responsible for launching the immune system, affecting inflammatory homeostasis and immune regulation in neonates and young children. Environmental factors, such as birth mode, diet early in life, and use of antibiotics can influence gut microbiota composition and can to lead to lower bacterial diversity, decreased SCFA production and increased gut permeability. The microbiome is the community of microorganisms that exists in a particular environment. In humans, the term is often used to describe the microorganisms that live in or on a particular part of the body, such as the skin or gastrointestinal tract. Beneficial microbes such as rhizobacteria and mycorrhizal fungi can help plants to 'deal' with pathogens and herbivorous insects as well as to tolerate abiotic stress.

Bacteria and their main predators, protists, account for more than 40 times the biomass of all animals on Earth. As a result, they have a huge effect on carbon dioxide emissions. Microbes are involved in many processes, including the carbon and nitrogen cycles, and are responsible for both using and producing greenhouse gases such as carbon dioxide and methane. Microbes can have positive and negative responses to temperature, making them an important component of climate change models. The most significant effect of the microbes on earth is their ability to recycle the primary elements that make up all living systems, especially carbon, oxygen, and nitrogen. Primary production involves photosynthetic organisms which take up CO2 from the atmosphere and convert it to organic material.
