How does a sense of smell help it survive?

Please provide me with the context of "it" - which animal or organism are we talking about?

The sense of smell is crucial for survival in many ways, but the specific benefits vary depending on the species.

For example:

* Predators: A keen sense of smell helps them locate prey, even over long distances.

* Prey: A strong sense of smell helps them detect predators and avoid danger.

* Animals that forage for food: Smell helps them find food sources like fruits, fungi, or carrion.

* Social animals: Smell plays a vital role in communication, recognizing individuals, marking territory, and attracting mates.

Let me know which animal or organism you have in mind, and I can explain how their sense of smell helps them survive in detail.
