| 1. What are the different ways in which microbes are used in human welfare? |  |
Ans. Microbes are used in various ways in human welfare. They are used in the production of antibiotics, vaccines, enzymes, and organic acids. They are also used in sewage treatment, bioremediation, and in the production of food and beverages.
| 2. How are microbes used in the production of antibiotics? | |
Ans. Microbes are used in the production of antibiotics through a process called fermentation.

This helps in the purification of water before it is released back into the environment.
| 4. Are there any harmful effects of microbes in human welfare? | |
Ans. While microbes play a significant role in human welfare, some can also have harmful effects. Certain pathogenic microbes can cause diseases in humans and animals. It is important to maintain proper hygiene and follow safety measures to prevent the spread of these harmful microbes.

Ans. Microbes are used in the production of various food and beverages. For example, yeast is used in the fermentation process to produce bread, beer, and wine.
