Symbiosis in the human body by Benjamin Sloat on Prezi
A common example of parasitism with humans is ticks. As we know, symbiosis is an association between two organisms in an ecosystem. benefiting from the human sebum in its sheltered eco- logical follicular mites normally have a symbiotic relationship with hu- mans. In usual. The symbiotic relationship between the human and the mosquito is Demodex parasites are microscopic mites who live in the skin and hair of.
An example of amensalism is when a large tree and a sapling are growing in the area. The large tree collects most the rainwater and soil nutrients, causing the sapling to die. By the decay of the sapling the large tree gains nutrients. For example humans drop skin particles and dust mites eat them. You can imagine the effect to the dust mite population should the humans be killed off.

Assuming humans were the only source of food for the dust mites. Now translate that effect to the eco system which we harm everyday with the use of pesticides. Pesticides that are used on farms world wide, causing countless traumatic effects that we may not even be aware of yet. Lets use the Pesticides that are used in the vineyards in the Napa Valley as an example of the harm that is being inflicted on the environment. Pesticides are sprayed in vineyards to attempt to kill off aphids and other harmful pests, but can contaminate the crop as well.

How many people haven't had strep throat? Strep throat is a disease caused by Streptococcus pyogenes, which lives commensalistically in our own digestive tract. However, when these bacteria find their way into one's throat or onto one's skin, they typically behave as parasites.
Streptococcus pyogenes Good microbe gone bad? Streptococcus pyogenes in the wrong place. All scientists are not in agreement on the subject of commensalism, objecting that there is always a cost to a symbiotic relationship.
These microscopic mites live on your face
Indeed, studies have linked even our genteel Demodex mites to instances of trouble making. Roseacea and eczema are both conditions that result from our own immune response to a foreign material. The structure of symbioses therefore appear to form a continuum. On one end are associations between organisms that are, in theory, equally beneficial and truly mutualistic and, at the other extreme, there are the parasitic relationships in which one organism benefits while the other is harmed.
