What giraffes with longer necks have an advantage in?

Giraffes with longer necks have an advantage in reaching higher foliage and leaves, allowing them to access food sources that shorter individuals cannot. This ability to browse on tall vegetation helps them compete more effectively for resources, especially in environments where food is scarce. Additionally, longer necks may play a role in mating displays and combat, as males with longer necks often have an advantage in fights for dominance and attracting mates.
