Question

Why do we say all microorganisms are not harmful give two examples ?

Answer 1

Answer:

It is so because some really are helpful to us.

For ex. Yeast is a unicellular fungi. You may think of only something decaying when you here the word fungi but yeast is used in making bread and in the process of fermentation.

E. coli are also very helpful to us as they can be used in various bio technological processes and are also available in a lot of amount.

Hope it helps..
