What is competition?

Define the word competition as it might be related to the field of ecology.

Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another. Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another.

Intraspecific competition: The same species compete for resources.

Interference competition: fighting / disrupting.

Exploitative: Share resources.
