What is the difference between an organisim's and it's niche?

An organism refers to an individual living entity, such as a plant, animal, or microorganism, that has its own biological characteristics and behaviors. Its niche, on the other hand, encompasses the role it plays within its ecosystem, including how it obtains resources, interacts with other organisms, and contributes to energy flows and nutrient cycles. While an organism is a specific life form, its niche describes its functional position and the specific environmental conditions it requires to thrive. In essence, the organism is the "who," and the niche is the "what, where, and how" of its existence.
