Parasitism Flashcards
define symbiosis
a continuum of interactions between heterospecifics
what are the levels of symbiosis
mutualism –> commensalism –> parasitism –> parasitoids –>predation
define mutualism
beneficial for both parties
define commensalism
one party benefits and the other neither benefits nor suffers
define parasitism
one organism depends on another by living on or in it while the host suffers slightly. the parasite is adapted to keep its host alive while feeding on it
define parasitoidism
when the parasite lives off its host eventually killing it as part of its overall plan
define predation
the outright consumption of one organism by another
define hyperparasitism
a parasite whose host is also a parasite
what is the most common phylum of faunal parasite
arthropods
define ectoparasitism
when a parasite exploits its host from outside the host
define endoparasitism
when a parasite exploits its host from inside the host
define social parasitism
when social interactions between hosts are exploited by parasite
define kleptoparasitism
the theft of resources from other organisms
define brood parasitism (cuckoo)
when eggs are laid in a heterospecific’s nest
how can a host birds prevent being a victim of brood parasitism?
by laying many eggs they can lessen the chances of a cuckoo egg being raised as the mother will have more of her own young to look after
