What is the role of micro-organisms in nature?
Microorganisms are found everywhere in the environment and play a leading role in countless natural processes.
Among other things, they operate the basic drug cycles that are necessary for the plants’ supply of nutrients via the reaction of organic matter in soil..
Which bacteria is used in agriculture?
They are Azotobacter, Clostridium and Rhizobium spp. They fix free nitrogen of the soil and make it available to the plants. The first two bacteria live freely in soil and fix the atmospheric nitrogen in the form of nitrogenous compounds in the soil. The third one is a symbiotic type.
What is definition of agriculture?
Agriculture is the science, art and practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities.
What are the harmful effects of microorganisms?
Microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease. Different diseases are caused by different types of micro-organisms.
What are the roles of microorganisms?
Microorganisms have several vital roles in ecosystems: decomposition, oxygen production, evolution, and symbiotic relationships. Decomposition is where dead animal or plant matter is broken down into more basic molecules. This process only happens because of the microorganisms that find their way into the dead matter.
Which part of the body has the most bacteria?

What is the role of microorganisms in agriculture?
Soil microbes (bacteria and fungi) are essential for decomposing organic matter and recycling old plant material. Some soil bacteria and fungi form relationships with plant roots that provide important nutrients like nitrogen or phosphorus.
What are 5 helpful microorganisms?

How do microbes benefit the environment?
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 (N). … Thus along with all these benefits, microbes greatly contribute in maintaining sustainability of environment.
What is the role of microorganisms in the human body?
For example, each human body hosts 10 microorganisms for every human cell, and these microbes contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals. And, of course, microbes are essential to making many foods we enjoy, such as bread, cheese, and wine.
