Verified step by step guidance1
Understand the key terms: A 'habitat' refers to the physical environment where an organism lives, such as a forest, desert, or ocean. A 'niche,' on the other hand, refers to the role or function of an organism within its habitat, including its interactions with other organisms and its use of resources.
Analyze the first option: 'The habitat is the set of behaviors an organism exhibits in its environment.' This is incorrect because behaviors are part of an organism's niche, not its habitat. The habitat is strictly the physical environment.
Analyze the second option: 'The niche and habitat are identical and can be used interchangeably.' This is incorrect because the niche includes more than just the physical location; it encompasses the organism's role, behaviors, and interactions within the ecosystem.
Analyze the third option: 'The habitat is where an organism lives, while the niche is its role within that environment.' This is correct because it accurately distinguishes between the physical location (habitat) and the functional role (niche).
Analyze the fourth option: 'The niche refers only to the physical space an organism occupies.' This is incorrect because the niche includes not just the physical space but also the organism's interactions, behaviors, and ecological role.
