NEET BIOLOGY

Detailed explanation-1: -Microorganisms are ubiquitous; that is, they are present nearly everywhere.

Detailed explanation-2: -Microbes have astronomical abundance on a global scale. As a consequence, species are ubiquitous, so speciation and extinction are rare, the global number of microbial species is relatively small, and local species richness is a large pro-portion of global species richness.

Detailed explanation-3: -They are found in every conceivable habitat, from the soil that we use to grow our food to our digestive systems that we use to digest our food. To survive and reproduce in any habitat, microbes must be able to obtain energy, deal with toxins, and handle competitors and predators.

Detailed explanation-4: -Microbes are tiny living things that are found all around us and are too small to be seen by the naked eye. They live in water, soil, and in the air. The human body is home to millions of these microbes too, also called microorganisms.

Detailed explanation-5: -Definition. Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet’s ecosystems.
