Final answer:
A silverback is an adult male gorilla, recognized by the silver hair on their back and serving as the leader of their troop with responsibilities including decision making and protection.
Step-by-step explanation:
A silverback is the term used to describe an adult male gorilla, typically more than 12 years of age. The name derives from the distinctive patch of silver hair on their back, which develops as they mature. Silverbacks serve as the leader and protector of a troop, consisting of females and offspring. These dominant males take on the responsibility of making decisions for the group, mediating conflicts, leading the troop to various feeding sites, and protecting them from threats.
Silverbacks are known for their impressive size and strength, which can be intimidating to predators and rivals. Despite their formidable appearance, they are predominantly herbivorous, feeding on a variety of vegetation, such as leaves, stems, and fruit. In the wild, silverbacks play a critical role in the social structure and survival of gorilla populations.
