Carnivorous animals - lions and leopards, occupy the same niche but lions predate mostly larger animals and leopards take smaller ones. This mechanism of competition is referred to as
Resource partitioning is a mechanism by which two competing species and avoid competition and co-exist. As lions predate mostly larger animals and leopards take smaller ones, they avoid competition with each other.
An organism is said to behave altruistically when its behaviour benefits other organisms at its own cost.
Character displacement is an evolutionary change that occurs when two similar species inhabit the same environment. Under such conditions, natural selection favors a divergence in the characters in order to avoid niche overlap or competition exclusion.
When resources are limited, the competitively superior species eliminates the inferior species. This is competitive exclusion.
