Which term describes a group of animals that is self-organized by rank?

A) selfish herd
B) dominance hierarchy
C) pack
D) social group
E) culture

A dominance hierarchy is a system where individuals rank themselves within a group based on factors such as age, size, strength, or aggression. The animals at the top of this hierarchy have priority access to resources such as food or mates, while those at the bottom have lower status and fewer opportunities. This type of organization is seen in many social animals, including primates, elephants, and wolves. The other options are not as specific to this type of organization. A selfish herd describes a behavior where animals try to position themselves in the middle of their group to reduce their own risk of predation, regardless of individual rank. A pack or social group simply refers to any group of animals that interact with each other to some degree. Culture is a concept specific to humans and refers to the transmission of learned behaviors, beliefs, and values between generations.
