interactions among organisms Flashcards
types of interaction
intraspecific relationship
interspecific relationship
population ecology interaction in which members of the same species fight for a restricted number of resources
intraspecific relationship
any relationship involving the coexistence and interaction of two or species. when a larger animal consumes the flesh of a smaller animal
interspecific relationship
two male birds of the same species
intraspecific relationship
marine mammals or species that often eat the same type of fish in the ocean ecosystem
interspecific relationship
naturally occuring interaction or close living relationship between organisms of different species that benefits one or both parties
symbiosis
it has a long lifespan
obligate symbioses
symbioses that are more recent behavioral adaptations that can evolve into obligate symbioses given enough time
facultative symbioses
types of symbiotic relationship
mutualism
commensalism
parasitism
interactions between organisms of two different species in which each organism benefits in some way from the other
mutualism
it can involve the exchange of resources like shelter, food, and other nutrients, or services like protection, transportation, and healthcare
mutualism
relationship between two species, in which both are completely dependent on each other. neither the participant could survive without the other
continuous association
type of mutualism in which the interacting species derive benefit from each other but not being fully dependent that each other cannot survive without the symbiotic partner
transitory association
relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter
commensalism
organism that benefits
commensal
