Explain the basic relationship between humans and microorganisms Solution Answer= The basic relationship between humans & microorganisms are as follows The surfaces of human body inside & outside ,for example skin ,mouth & intestines are covered in millions of individual microbes The microbes that do not harm in fact they helps to protect us becoming infected with harmful microbes they are known as normal body flora There are 3 types of symbiotic relationships between humans & bacteria 1] Commensalism = Is a relationship that is beneficial to the bacteria ,but does not help or harmthe host most are reside on epithelial surfaces that come in contact with the external environment commonly found on skin ,respiratory tract & gastrointestinal tract They aquire nutrients & place to live & grow from their host some are pathogenic & cause disease may provide benefit to host 2] Mutuliastic relationship-= Both bacteria & host are beneficial for example there are several kinds of bacteria that live on skin & inside the mouth ,nose,throat & intestines of humans These bacteria received a place to live & feed while keeping other harmful microbes from taking up residence bacteria in digestive system assist in nutrient metabolism ,vitamin production & waste processing 3] Parasitic relatioship= is one in which the bacteria benefit while the host is harmed pathogenic parasites ,which cause disease,do so by resisting the hosts defences & growing at the expense of host These bacteria produces poisonous substances called endotoxins & exotoxins are responsible for the symptoms to occure with an illness Disease causing bacteria are responsible for a number of diseases including meningitis ,pneumonia .tuberculosis& several types of food borne diseases.

1. Explain the basic relationship between humans and microorganisms
Solution
Answer=
The basic relationship between humans & microorganisms are as follows
The surfaces of human body inside & outside ,for example skin ,mouth & intestines are covered
in millions of individual microbes
The microbes that do not harm in fact they helps to protect us becoming infected with harmful
microbes they are known as normal body flora
There are 3 types of symbiotic relationships between humans & bacteria
1] Commensalism = Is a relationship that is beneficial to the bacteria ,but does not help or
harmthe host
most are reside on epithelial surfaces that come in contact with the external environment
commonly found on skin ,respiratory tract & gastrointestinal tract
They aquire nutrients & place to live & grow from their host
some are pathogenic & cause disease may provide benefit to host
2] Mutuliastic relationship-=
Both bacteria & host are beneficial
for example there are several kinds of bacteria that live on skin & inside the mouth ,nose,throat
& intestines of humans
These bacteria received a place to live & feed while keeping other harmful microbes from taking
up residence
bacteria in digestive system assist in nutrient metabolism ,vitamin production & waste
processing
3] Parasitic relatioship= is one in which the bacteria benefit while the host is harmed
pathogenic parasites ,which cause disease,do so by resisting the hosts defences & growing at the
expense of host
These bacteria produces poisonous substances called endotoxins & exotoxins are responsible for
the symptoms to occure with an illness
Disease causing bacteria are responsible for a number of diseases including meningitis
,pneumonia .tuberculosis& several types of food borne diseases
