Question

Where do we find Bacteria?

Answer 1

Presence of bacteria:

1. Bacteria are parasites with a smaller cell structure than many other organisms. A single loop of DNA carries its control center, which contains genetic information.
2. Rather than a nucleus, some bacteria have a plasmid, which is an extra circular genetic material. Genes that provide bacterium an edge over other bacteria are typically observed on the plasmid.
3. Bacteria are found in all kinds of habitats on Earth, such as soil, rock, oceans, and even arctic snow.
4. Some organisms including plants, and animals including humans, exist in or on other organisms. In the human body, there are approximately ten times as many bacterial cells as human cells.
5. Most of these bacterial cells can be found in the lining of the digestive tract. Bacteria can be found in the soil or on decomposing organic material, where they play an important role in nutrient cycling.
6. Some kinds spoil food and damage crops, and others are essential in the production of fermented foods like yogurt and soy sauce. Just a small proportion of bacteria are parasites or pathogens that affect animals and plants.
