In ecology, what does the term "niche" refer to?

The term "niche" in ecology specifically refers to the role and position of a species in its environment. This concept encompasses several factors, including how an organism interacts with other organisms (both species and different types) and how it utilizes resources such as food, shelter, and other necessities for survival and reproduction. A niche describes not only where a species lives (its habitat) but also how it contributes to the ecosystem, including its behaviors, feeding habits, and its interaction with abiotic factors like light and water.

Understanding a species' niche is crucial since it highlights the importance of biodiversity and how different species work together in an ecosystem. Each species has its unique niche that allows for various organisms to coexist without directly competing for the same resources, thus maintaining ecological balance.
