Predation

Competition
? occurs between members of the same species.
For example, two male birds of the same species might compete for mates
in the same area.
Intraspecific competition
? occurs between members of different species.
For example, predators of different species might compete for the same prey.
Interspecific competition
is a close relationship between two species in which at least one
species benefits.
Symbiosis
A ? is an arrangement of the organisms according to the order of
predation in which one uses another as a food source.
food chain
The ? refers to the
position of organisms in the food chain
trophic level
