Answer:
DArwin's finches, anole lizard of the Caribbean island
Step-by-step explanation:
The habitat is the natural abode for the species. They dwell here and do things to survive. In a single habitat, many different species are living. They share shelter and food.
The niche is the activity or profession of the species in the habitat. It is the characteristics of the animal which distinguishes itself from others. The habitat and niche of the species are almost different to reduce the competition.
If both are the same then the competition will be rigorous. It leads to the elimination of weaker species. This is the very reason due to natural selection in the same habitat species have a different niche.
The species have the same character, separate from each other and reside in different geographical areas. This is called separation of niche which reduces the competition.
e.g Darwin's finches, anole lizards of the Caribbean island.
