Intro Flashcards
Predator-prey symbiosis
One symbiont benefits at the expense of the other
Phoresis symbiosis
Smaller symbiont is mechanically carried about by the larger symbiont
Mutualism
Both symbionts benefit
Commensalism
One symbiont benefits and the other neither benefits nor is harmed
Parasitism
One symbiont (parasite) lives in or on the other symbiont (host), deriving nutrition and/or protection from the host at some point in its life, and provides no benefit to the host
Ectoparasite
- Lives on the body of the host
- Transmission of disease-causing organisms
- Agents of disease
Endoparasite
Lives within the body of the host
Aberrant (erratic) parasite
Parasite moves from its usual site of infection into a location it ordinarily does not live
Incidental parasite
Parasite occurs in a host in which it does not usually live
Facultative parasite
Organism that is normally nonparasitic becomes parasitic under certain circumstances
Obligatory parasite
Organism that must lead a parasitic existence
Periodic parasites
Organism that makes frequent, short visits to obtain nourishment
Pseudoparasite
Organism that is not a parasite but is mistaken for one
