The unseen majority: soil microbes as drivers of plant diversity and productivity in Terrestrial ecosystems. Eco Letters. 11(3):296-310.This peer-reviewed journal explains the impact that soil microbes have on the ecosystem. Microbes are typically thought to have a negative effect on their host, however there are many benefits to having bacteria in the soil. It has the ability to enrichnutrients in soil, while maintaining diversity in the ecosystem. Microbes can also act as pathogens and feed on the plants nutrients, depriving the plants of it’s needs. As a result, the plant becomes dependent upon this symbiotic relationship between the microbe and plant and the microbe plays a crucial role in the plants survival. Both the positive and negative effects contribute to the importance of microbes living in soil. Wang L, Tuo Y, Chunxiu G, Fugui H, Fangling W, Tao S, Yinhua Z. 2015. Research progress of soil microbiology. Agric Science & Tech. 16(11):2367-2371.This article suggests that microbes are helping to restore the ecosystem. There are many benefactors to having microbes in soil. For instance, microbes facilitate decomposition of organic matter resulting in enriched soil and exponential plant growth. Specific microbes including cellulose-decomposing microbes are seen to increase nutrients in soil, which is of great economic and ecological importance. This, in turn, creates new species of plants that inhabit the earth. This research is very important on a global scale and needs to be further continued as time
