Question

What kinds of organisms/entities are considered microorganisms? What feature do they all share?

Answer 1

Organisms are classified by taxonomy into specified groups such as the multicellular animals, plants, and fungi. Unicellular microorganisms such as a protists, bacteria, and archaea. All types of organisms are capable of reproduction, growth and development, maintenance, and some degree of response to stimuli. A microorganisms are organisms, which are microscopic. Microorganisms can be bacteria, fungi, archaea and protists but not viruses and prions, which are generally classified as non-living.

Microorganisms live almost everywhere on earth. They act as decomposers in nutrient recycling in surroundings . Other microorganisms live in nodules on the roots of some plants, which convert nitrogen from the air to a form usable by plants. Microorganisms multiply rapidly under good growth situations and contributes benefit to the larger plant and animal host organism and exists in healthy dynamic balance with other microorganisms and the host organism. Pathogenic microbes can attack larger organisms, which dominate that organism's defenses and cause disease. There are numerous characteristics shared between humans and microorganisms, which include a carbon-based biochemistry with genetic material , the presence of cell membranes, required for energy and metabolism process. Bacteria and protists are living symbiotically in the gut of such even-toed ungulates like as cattle, deer, goats, and sheep, break down cellulose into a digestible simpler form of carbohydrate and allowing the host animals to consume and digest the most abundant organic compound on earth. Microorganisms are also important in food production by humans, being used in brewing, baking, and other food-making processes.
