Properties of microorganisms of medical importance on biology discussion

Answer 1

Bacteria are microscopic organisms, which are often known as 'germs' and 'microbes'. They are among the simplest forms of life known, and, hence show the characteristics of both plants and animals. Their relationship to other living organism is very obscure.

Bacteria play important roles in the global ecosystem. The ecosystem, both on land and in the water, depends heavily upon the activity of bacteria. The cycling of nutrients such as carbon, nitrogen, and sulfur is completed by their ceaseless labor.
