Harmful Microorganisms
Disease and decay are not inherent properties of organic objects, nor are they caused by physical damage, it is microorganisms that bring about these changes. We are surrounded by bacteria, virus, and fungi. Many cause diseases in cattle and crops and others are known for entering human bodies and causing various diseases.
Examples of familiar human diseases are:
Bacteria: pneumonia, bacterial dysentery, diphtheria, bubonic plague, meningitis, typhoid, cholera, salmonella, meningococcal
Virus: Chickenpox, measles, mumps, German measles, colds, warts, cold sores, influenza
Protoctista: amoebic dysentery, malaria,
Fungi: ringworm, athlete’s foot

Decomposers Bacteria and most Fungi are saprotrophic and have an important role in an ecosystem as decomposers, they break down dead or waste organic matter and release inorganic molecules Green plants take these nutrients which are in turn consumed by animals, and the products of these plants and animals are again broken down by decomposers.
Yeast is a single-celled fungus that lives naturally on the surface of the fruit. It is economically important in bread-making and brewing beer and also in the making of yogurt.
