What does niche mean in science?

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).

Informally, a niche is considered the “job” or “role” that a species performs within nature.
