ECOLOGY Flashcards
(16 cards)
It is a physiochemical features of the environment such as temperature, humidity and pH; it can vary with time and space.
CONDITIONS
It is consumed by the organism in the course of maintenance, growth and reproduction.
RESOURCES
It is a large-scale biological communities which is shaped by the regional conditions of the environment.
BIOMES
It is directional or progressive change in a community and occurs over a period of months.
SUCCESSION
It assumes that there is a single end point that succession is leading for and is generally defined by the climate.
MONO CLIMAX / FACILITATION HYPOTHESIS
The priority effects influence the composition of communities where those that colonize it first are the dominant species.
INHIBITION MODEL HYPOTHESIS
It states that there are no ecological interactions and it follows null theory where all species are equal and succession is entirely stochastic with primary effects from the birth, death rates and dispersal.
NULL SUCCESION HYPOTHESIS
It is a location that provides the characteristic conditions and resources that allow a species to thrive.
NICHE
A limitation with this model of population growth is that it assumes populations grow infinitely, and from observations this doesn’t occur something limits them.
EXPONENTIAL
This model of population growth includes the carrying capacity and density/dependence looking at competition. It has however doesn’t incorporate a range of competitive intensities and is doomed to perfectly compensate density dependence.
LOGISTIC
It is a ecological relationship that when two or more organisms rely on the same environmental resource
COMPETITION
It is a ecological relationship twhuch behavior of one animal feeding on another
PREDATION
It is a ecological relationship which is the close relationship of two dissimilar organisms.
SYMBIOSIS
It is a ecological relationship which a symbiotic relationship where both organisms benefit.
MUTUALISM
It is a ecological relationship where one organis benefits and one does not benefit but is unharmed.
COMMENSALISM
It is a ecological relationship where one organism benefits and one is harmed.
PARASITISM
