Answer 1

Q1: No. All microorganisms or microbes are not pathogens. Most microbes can’t hurt you, and many of them are beneficial to the environment or your body. In fact, life on Earth couldn’t even exist without microbes! But a few microbes, called pathogens, grab all the headlines because they’re the ones that cause diseases in humans.
Most microbes on Earth are beneficial to life and to humans. Microbes in the environment are nature’s recyclers. They break down the molecules in dead organisms and make them available again to living things. Humans harness the power of microbes for the production of fermented food like wine and cheese and for industrial applications like paper production.
The bacteria that normally live in and on your body are your normal microbiota, and they protect your health by making your body less vulnerable to pathogens and by producing vitamins that aid with digestion and blood clotting.
A small percentage of microbes cause infectious diseases in humans.Infectious diseases are simply those diseases caused by things that can spread, like bacteria and viruses. To cause disease, microbes must be able to enter and colonize your body, overcome your immune system’s defenses, and cause damage to your body.
