Question

state the beneficial effects ( or usefulness ) of micro - organisms in our lives .​

Answer 1

Bacteria and fungi are required to maintain a healthy environment. Not only do they recycle natural wastes and dead animal and plant matter, they also produce many of the nutrients that plants need to grow. Bacteria, in particular, are the only living things that can fix nitrogen for use in plants. At the same time, microorganisms work in tandem with certain plants to aid them. Some viruses have been found to provide heat resistance to grasses in arid locations, and many plants store bacteria in their roots to help absorb certain nutrients more easily.
