Abundance
The quantity of a particular species present in a given area.
Adaptation
feature of an organism that makes it better suited to its environment
parasitism
one organism benefits, one is harmed (dog and ticks)
commensalism
one organism benefits, one organism is unaffected (clown fish and anemone)
mutualism
both organisms benefit (hummingbird and flower)
Behavioural adaptation
A change in behavior that helps an organism survive in its environment (birdcalls, migration)
Autotroph
An organism that produces its own food from inorganic substances.
Carrying capacity
The maximum number of individuals of a species that an environment can support.
Community

Density
The number of individuals per unit area or volume.
Distribution
The way in which a species is spread out across a given area.
Ecological niche
The role and position a species has in its environment.
Ecosystem
A community of living organisms and their interactions with their environment.
