Answer:
A.) They cause various diseases to us. They spread & infect other human beings
B.) They spoil our food , making it undesirable to consume ( food poisoning , food borne illness) , also affect our crops by causing disease in crop plant and hence affecting crop yield.
C.) They also responsible for damaging other things such as leather, clothes etc.
D.) Microorganisms cause Diseases in Humans, Plants, Animals etc.
E.) Microorganisms Spoil Food, Clothing, and Leathers.
F.) Such Disease Causing Microorganisms are Known as Pathogens.
G.) In Cattle, The food and Mouth Disease caused by a Virus.
H. )The Productivity of Wheat, Orange, Apple etc. is Reduced due to Microbial Diseases in Plants.
I.) Certain microorganisms can form biofilms on surfaces and even pipelines etc. If they get some ambient nutrients and environment. These biofilms are hard to destroy as they protect microorganisms from external abuse allowing them to concentrate in numbers.
J.) Several of them are pathogenic in nature but there is a lot of scare around them. One has to be aware that any organisms can cause problems when they are exceedingly large (more than the threshold) in numbers, more than what our immune system can immediately encounter or if they gain direct access to blood.
