Detailed explanation-1: -Niche is of four types namely: Habitat niche, Food niche, Reproductive niche and Physical & Chemical Niche.
Detailed explanation-2: -Fundamental niche is the entire set of conditions under which an animal (population, species) can survive and reproduce itself. Realized niche is the set of conditions actually used by given animal (pop, species), after interactions with other species (predation and especially competition) have been taken into account.
Detailed explanation-3: -An example of how a realized niche is formed is the coexistence of wolves and coyotes living across North America. Because both species inhabit the same area, coyotes would then compete for food and territory. The realized niche for coyotes was small due to the more aggressive nature of wolves.
Detailed explanation-4: -In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition).
