The fundamental niche of a species is the range of abiotic conditions under which species can persist. 

This includes the range of temperature, humidity, and salinity conditions that allow a population to survive, grow, and reproduce.

The range of abiotic and biotic conditions under which a species persists is its realized niche. 

The realized niche determines the geographic range of a species or of various populations that compose a species.

No two different species can share the same niche but can have similar niches,  this is because of competition for resources like food, space etc

Two species cannot coexist permanently in a community if their niches are  identical
