Q.

Which of the following is correct about microbes?

1. They are small living organisms just like bacteria.

2. They are chemical fertilizers and used as surfactant.

3. They are plants that grow inside oil reservoir.

4. Microbes cannot be used for processing food products.

Q.

2. they secrete oil.

3. they increase natural pressure.

4. they decrease natural pressure.
