The study of micro-organisms - viruses, bacteria and fungi
Viruses
Can only reproduce inside living cells - they all cause disease. They cause colds, flu, measles, mumps and AIDS.
Bacteria

Soil bacteria
Break down (decompose) dead plant and animal material and release their nutrients back to the soil.
Harmful bacteria
Cause diseases, food spoilage and tooth decay.
Fungi
Used in brewing, baking, making antibiotics and some are edible.
Harmful fungi
Cause animal and plant diseases, food spoilage and are poisonous
Biotechnology
The use of living things (micro organisms) to make useful substances. Examples are using bacteria to make cheese; yeast to make alcohol
