Question

Where can microbes live?

Answer 1

Microbes are also known as microorganisms that are found all around us in almost everything that surrounds us. They are very minute and cannot be seen with the naked eye. They are adaptive in nature and can adjust easily in all types of conditions.

Complete answer:
Microbes are that organisms that are very tiny in nature and can only be seen under the microscope. They may be unicellular or multicellular and may either be harmful or beneficial depending upon their characteristic features. Microbes are said to have cosmopolitan distribution as they may live in all types of environments and various conditions. They are even found in harsh conditions as well like extreme cold or hot areas as in ice or in volcanoes. They may be found in highly saline water, etc. They are found in all types of habitats that include poles, equator, deserts, ice-cold waters, hot molten lava, etc. they are quite flexible and may easily adapt to their environment. Microorganisms are omnipresent. They are present everywhere, from cold climates like ice to hot climates like hots springs and deserts, inside or outside the body, free or alone, air, water, etc.
-Microorganisms are classified into 5 groups:
1. Bacteria
2. Fungi
3. Protozoa
4. Algae
5. Virus
-Viruses are dead but become living when entering the host body.
-Microorganisms play an important role in our life, some may be useful.
-They are used in making curd, bread, preparation of medicines (antibiotics), cleans the environment, increases soil fertility.
-They are used for commercial purposes in alcohol industries through fermentation.
-Some microorganism causes diseases in plants and animals (humans) both.
-In animals, it mostly causes tuberculosis (bacteria), malaria (protozoa), common cold (virus), etc.
-In plants, it causes citrus canker (bacteria), rust of wheat (fungi), yellow vein mosaic in okra (virus), etc.
-The microorganisms which cause disease are called pathogens.

Note:
The discovery of microbes is done mainly by two scientists, one is Robert Hooke in 1665, who described the molds and their fruiting structures. While the second one is Antoine Van Leuwenhoek in 1676 who described the cell of bacteria.
