Which of the following best describes an ecological niche?

• A. The physical space an organism occupies
• B. The interactions of a species within its ecosystem
• C. The specific diet an organism follows
• D. The shelter an organism uses

Answer: (B)

An ecological niche encompasses the role and position a species plays within its ecosystem, which includes not only where it lives but also how it interacts with other organisms and its environment. This concept involves various factors such as resource use, habitat preferences, and relationships with other species (like predation, competition, and mutualism). In this sense, option B accurately captures the complexity of an ecological niche because it highlights the interactions that define how a species fits into the larger ecological community. This definition goes beyond just location, as it includes the environmental conditions and the biological relationships that shape an organism's existence within its ecosystem, making it a more comprehensive and accurate description of what an ecological niche is.
