Hint: Microorganisms are the minute organisms invisible to the eye. Microorganisms are so small that they will only be seen under a microscope. They exist as unicellular, multicellular, or cell clusters and can be divided into: bacteria, archaea, fungi, protozoa, algae, and viruses.

Complete step-by-step answer:
Microorganisms refer to a large range of organisms like bacteria, viruses, fungi, algae, protozoa, etc. some harmful microbes, as an example but 1% of bacteria, can invade our body (the host) and make us ill.
Microorganisms - Harmful Effects on Organisms & Ecosystems: The primary harmful effects of microbes upon our existence and civilization is that they're a very important reason behind disease in animals and crop plants, and that they are agents of spoilage and decomposition of our foods, textiles and dwellings.
Microbes Cause Infectious Disease: A microbe which is capable of causing communicable disease in an animal or plant is termed a pathogen. Four groups of microbes contain pathogens: bacteria, fungi, protozoa and therefore the viruses. Only the archaea and algae are lacking pathogens. Pathogens are the explanation for infectious diseases.
Microbes Cause Food Spoilage and Decomposition: Microbes are the agents of food spoilage and decomposition of clothing and sheltering materials. The factors that allow microbes to accomplish biodegradation and carbon cycling are at work on everything organic, which has foods and grains stored in granaries, supermarkets or refrigerators, moreover as natural structural materials and textiles used for our shelters and clothing. Nothing lasts forever, and also the microbial decomposition of everything organic will occur in time. Fungi and bacteria are the most important microbial agents of decomposition in aerobic environments. Bacteria take over in environments that lack oxygen.
Spreading of diseases: Micro-organisms cause diseases in animals. For instance, in humans, bacteria cause diseases like tuberculosis, cholera, typhoid, etc.
Surfaces where the microbe resides: It spreads the harmful and poison where it resides. For instance if it resides on a grimy place like stagnant water so it carries the dirt and resides on food which is kept open. In conclusion, microorganisms are all around us. From the chair that we sit to the keyboards that we type, our surroundings are home to billions of microscopic organisms. Moreover, we even have microbes living in our gut that play a very important role in our digestive health. In other words, most microorganisms aren't harmful, but we've to require precautions against those that are.

Note: Bacteria are unicellular organisms. They lack a nucleus and therefore are called prokaryotic. They exist in shapes of bacillus, coccus, spirilla , and vibrio. Most bacteria have a peptidoglycan cell wall; they divide by binary fission; and they may possess flagella for motility. The difference in their cell wall structure divides bacteria into Gram-positive or Gram-negative bacteria.
