Answer 1

So, due to this dual nature of microorganisms are said to be both a friend and a foe for us.

Microorganisms are useful to us because they help in processes like-

● Fermentation- This process uses a diversity of microorganisms which is used for the production of different products in food and alcohol industry.

● Curd formation- For making curd we always add a small amount of curd as inoculums into the milk which converts complete milk into the curd. Lactobacillus bacteria play a role in it.

Answer 2

Answer:

Microorganisms are useful in producing foods, treating waste water, creating biofuels and a wide range of chemicals and enzymes. They are invaluable in research as model organisms. They have been weaponised and sometimes used in warfare and bioterrorism.

Microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease. Different diseases are caused by different types of micro-organisms.
