Think of an ecological niche as a species' job description in its neighborhood. It’s not just the address (the habitat), but the hours, the menu, and all the drama with the neighbors. It covers everything: what it eats, what eats it, when it hunts, and how it reproduces.
Imagine a tree in a forest. Its niche isn’t just “being a tree.” It’s about how much sunlight it needs, what nutrients it pulls from the soil, and which animals use it for shelter. It’s the whole story of how that tree fits into the world.
