Transcript of symbiotic relationships project

Parasitism Symbiotic Relationships Deer Ticks attach themselves onto White Tailed Deer with their mouths to gain nutrition from the White Tailed Deers blood. Deer Ticks need this nutrition frequently in order to survive. The Deer Ticks goal is not to kill the White Tailed Deer though because it must still have a food source. However, in this relationship the White Tailed Deer is put at risk of infection and disease. White Tailed Deer can be found in North and Central America and Deer Ticks can be found in Central to Eastern America. Both of these organisms inhabit forests, fields, and other areas with much foliage. Example of Parasitism: White Tailed Deer and Deer Tick The only organism that benefits from this symbiotic relationship is the Deer Tick, this is what makes it is a Parasitic Relationship. A Deer Tick goes through 5 different life cycles and they must feed on at least 3 animals before moving onto the next cycle in their life. It can take up to 2 years for them to complete a life cycle but most die before finding a new host. Benefits White Tailed Deer Fun Facts Deer Ticks are the primary vector of Lyme disease. Deer Tick Fun Facts Parasitism is a symbiotic relationship in which one species benefits and the other is being harmed or even killed. Parasitism and Symbiosis http://www.ng.com/cranford/index.ssf/2009/08/deer_ticks_and_lyme_disease_in.html Sources Symbiosis is a close relationship between organisms of different species in which at least one organism benefits. White Tailed Deer have an average lifespan of about 10 years. A male White Tailed Deer can grow to be up to 450 lbs. Deer Ticks, in their adult stage, are about the size of a sesame seed. Deer Ticks must be attached to their host for at least 24 hours before any disease can be transmitted. http://www.uri.edu/ce/factsheets/sheets/deerticks.html http://www.cdc.gov/ticks/life_cycle_and_hosts.html animals.nationalgeographic.com/animals/bugs/deer-tick/ By:Kenna O'Brien
