Verified step by step guidance1
Begin by defining the term 'habitat'. A habitat is the physical environment where an organism lives. It includes factors like climate, terrain, and availability of resources such as food and water.
Next, define the term 'niche'. A niche refers to the role an organism plays within its ecosystem. This includes its interactions with other organisms, how it obtains its food, and how it contributes to the energy flow and nutrient cycle within the ecosystem.
Understand that a habitat is more about the 'where' an organism lives, focusing on the physical space and conditions. It is the 'address' of the organism.
Recognize that a niche is more about the 'how' an organism lives, focusing on its behaviors, interactions, and ecological role. It is the 'profession' of the organism.
Clarify the primary difference: A habitat is the physical environment, while a niche encompasses the functional role and interactions of the organism within that environment.
