What is the main purpose of microbes in the soil?
A
to release the nutrients in rocks
B
to cause disease
C
to feed animals
D
None of the above
Explanation: 

Detailed explanation-1: -Figure 1-Both bacteria and fungi help to feed plants by breaking down rocks to make the nutrients trapped within the rocks available to nearby plant roots. This process is called rock weathering. Microbes that perform rock weathering enrich soils with nutrients and help crops to grow better.

Detailed explanation-2: -These organisms have many tasks, and are central to crop fertility, purifying the environment from pollutants, regulating carbon storage stocks and production/consumption of many significant green house gases, such as methane and nitrous oxides.

Detailed explanation-3: -Soil microorganisms (figure 1) are responsible for most of the nutrient release from organic matter. When microorganisms decompose organic matter, they use the carbon and nutrients in the organic matter for their own growth. They release excess nutrients into the soil where they can be taken up by plants.

Detailed explanation-4: -By facilitating mineral dissolution and rock degradation, microbes enhance the release of elements from their geological reservoirs and perform significant elemental transformations.
