I apologize for the incorrect response. The behavior that is both territorial and used for courtship is sparring or wrestling using antlers or horns.

The behavior that is both territorial and used for courtship is dance rituals with potential partners. To understand this, let's break it down:

Behavior plays an important role in the natural world, including both territorial and courtship behaviors. Territorial behavior refers to actions taken by animals to defend and establish their territory, while courtship behavior involves actions taken to attract a potential mate.

Now, let's look at the given options:

1. Sparring or wrestling using antlers or horns: This behavior is primarily territorial. Male animals, such as deer or elk, often engage in sparring with their antlers to establish dominance over a specific territory. It is less related to courtship and more focused on territorial defense.

2. Dance rituals with potential partners: This behavior combines both territoriality and courtship. Many species of birds, for example, perform elaborate dance rituals to attract a potential mate and establish their territory at the same time. These dances serve as both a courtship display and a territorial signal.

3. Baring teeth as a sign of aggression: This behavior is primarily a sign of aggression, indicating the intent to intimidate or defend oneself. It is not directly related to courtship or territoriality.

4. Defending a nest from predators: This behavior is solely territorial and aimed at protecting the nesting area or offspring from potential predators. It does not involve courtship interactions.

In summary, dance rituals with potential partners is the behavior that combines both territoriality and courtship.
