Detailed explanation-1: -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).
Detailed explanation-2: -An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species’ niche includes all of its interactions with the biotic and abiotic factors of its environment.
Detailed explanation-3: -The environment can also lead to molecular, cellular, physiological or behavioural changes. For example, the expression of genes in an organism can be influenced by the external environment, such as where the organism develops or factors associated with where it is located.
