NEET BIOLOGY

Detailed explanation-1: -Habitat. Bacteria are ubiquitous, living in every possible habitat on the planet including soil, underwater, deep in Earth’s crust and even such extreme environments as acidic hot springs and radioactive waste.

Detailed explanation-2: -Germs especially like to live and grow in water when it is stagnant (not flowing) or when it is not treated with enough disinfectant, like chlorine. It is important to know where your tap water comes from and how to safely use it for purposes other than drinking.

Detailed explanation-3: -Bacteria live all over the Earth, in both aquatic and terrestrial environments. There are even bacteria who live in clouds. Many types live in soil and we’ll focus on these today. Some types of soil bacteria are photosynthetic and make their own food.

Detailed explanation-4: -Bacteria can be found in soil, water, plants, animals, radioactive waste, deep in the earth’s crust, arctic ice and glaciers, and hot springs. There are bacteria in the stratosphere, between 6 and 30 miles up in the atmosphere, and in the ocean depths, down to 32, 800 feet or 10, 000 meters deep.
