Answer 2

Answer:

Explanation:These are few ways that a microbe can be harmful.

Pathogenicity: These microbes have ability to cause infections destroy host and transmit to the next possible host.

Destroys host defence: Both 1st line and 2nd line of host defence is targeted and destroyed.

Antibiotic resistance: Many strains of bacteria are resistant to antibiotics which were actually developed as a result of inappropriate use of antibiotics against viruses and bacteria.

Food poisoning: Bacteria and viruses are the most common cause of food poisoning. The symptoms and severity of food poisoning vary, depending on which bacteria or virus has contaminated the food. Most food poisoning is caused by bacteria, viruses, and parasites rather than toxic substances in the food. But, some cases of food poisoning can be linked to either natural toxins (such as those in some mushrooms and pufferfish) or chemical toxins (such as pesticides or melamine). While some molds are desirable in foods (such as blue cheese), other molds can produce toxins that cause illness.

Food spoilage: Bacteria and fungi species are well known to cause food spoilage as they get enough nutrients and grow there release their contents and make food unfit for eating.

Biological warfare: Biological weapons include living organisms and biologically produced toxins to injure people, animals and destroy crops. These include harmful microbes such as Bacteria, viruses and spores. Toxins are produced by thses microbes. This causes mass destruction of populations.
