Protozoans- Protists like Algae can be used for food for human and animal consumption. They are plant like protists.
Viruses- They can be used to study other viruses and help to find cures for diseases. Also variagation of flowering maple leaves and tulips is caused by infection with specific viruses, creating a pretty striped design to the leaves and petals.

Answer 2

Sources of food/drink- Wine, Beer, Cheese, Yogurt, Cottage Cheese Sour Cream are all created by bacteria or fungi(yeast)
Used for baking - yeast (fungi)
Digestion (bacteria)
Fungi also have a symbiotic relationship with plant roots and they form mycorrhizae and allow plants to break down minerals in exchange for food

Most Viruses are harmful HIV/AIDS, HPV but
GBV-C is a nonpathogenic virus found in a large part of the human population, especially those exposed to blood-borne pathogens, the interest in the virus soared because of data pointing to its potential to antagonize HIV and thus block off the latter's harmful effects on the immune system

Some protozoans are harmful to man as they can cause serious diseases. Others are helpful because they eat harmful bacteria and are food for fish and other animals.

Answer 3

microorganisms are very useful in our normal life they are as follows

Bacteria- lactobacillus,E.coli and many bacteria are found in our intesteninal tract they helpful in our digestion

Virus- most viruses are harmful to humans but retrovirus only help in cloning

fungi- Penicillin and other fungi are help in antibiotic production

protozoan- are harmful to humans

Answer 4

Lots of ways. Some people are studying ways of using viruses in addition to chemotherapeutic agents to treat cancer. Bacteria are used to make yogurt, cheese, and other food products. Fungi make wine, and many antibiotics were originally fungally derived.
