A niche encompasses everything an organism does and needs to survive and reproduce. This includes:
* What it eats: Its food sources and how it obtains them.
* Where it lives: Its habitat and how it uses it.
* How it interacts with other organisms: Its relationships with predators, prey, competitors, and symbionts.
* Its role in the ecosystem: How it contributes to the flow of energy and nutrients.
For example, a lion's niche is that of a predator, while a tree's niche is that of a producer. No two species can occupy exactly the same niche in the same environment.
