Habitat vs niche: if many species share a habitat, how can each have a different niche?

I like ecology because it reads like prose, but the habitat vs niche part reads like a riddle.
NCERT says the place where an organism lives is its habitat, and that a habitat has many niches. The niche is the functional role or the "profession" of the organism. If I put it in my own words: habitat is the address, niche is the job.
But the next part is where I get tangled. If two species live in one pond, they share a habitat. Does this mean they must have different niches? What if they do the same job, e.g. two fish species both eating small insects? Does that break something?
I also saw that the chapter begins with ecology at four levels of biological organisation: organisms, populations, communities and biomes. But my other book writes ecosystem as a separate level as well. Which one do I follow in the exam?
Another doubt: if I say the niche of a tree in a forest is "its habitat + what it does", is that right? I've read this somewhere but I don't trust it.
Poetic explanations are welcome, but I do need a clean exam sentence 😊

Your "address and job" version is the one many students find helpful, and I'd keep it. For the exam, a more complete statement: niche = the functional role of a species in its habitat, including the range of conditions it can tolerate, the resources it uses, and its interactions with other organisms.
So your last line is not exactly right. Niche is not habitat plus function. The habitat is where it lives, and the niche is about what it does there and how, so they're related but separate ideas.

"The habitat is the address, niche the job and the rest of the day." I like that. Thank you all.

Two species can share a habitat and have different niches, e.g. different foods, different times of the day, different depths in the pond. If they have exactly the same niche, there is competition between them, and over time one may be driven out. That is the competitive exclusion principle (Gause's). That's why many co-existing species divide up resources, and NCERT talks about resource partitioning in a later section.

Habitat = niche. Same thing. Different words. Just remember one.

Aman, no, with respect. They are not the same. Habitat is a place (physical, a pond or a forest floor). Niche is a role or function in that place. One habitat holds many niches, e.g. a pond with a surface insect eater, a bottom feeder, a plant eater. You'd lose marks writing "same".

Ok. Noted. My mistake.

On the levels: the NCERT chapter begins with organism, population, community and biome. Many other books add "ecosystem" in between because that's how the ecosystem chapter later treats the system as a functional unit. If it is a direct NCERT-based question, go with NCERT's four. If the options list "ecosystem" as a level, it's usually fine as a level of organisation too, so you won't be marked wrong for knowing it, but read the question. My own rule: follow the text unless the question hints otherwise.

If it helps, my example for the habitat/niche difference: "a mango tree" lives in an orchard (habitat). Its niche includes providing food to bats and birds, shade, nesting space, using sunlight, taking up water, and so on. You can write several things in the niche but one place for the habitat.
