The revised paragraph with improved grammar and unnecessary words removed: Did you know that lions are sociable animals? They live in groups known as prides. Within a pride, the females remain together for life, allowing them to impart crucial knowledge to the cubs, such as the boundaries of their territory and the optimal locations for hunting and water sources. The females handle all the hunting. Meanwhile, the males are responsible for protecting the pride. A lion pride resembles an extended family. The paragraph contains four support sentences.

The revised paragraph is concise and carries improved grammar with unnecessary words omitted. Here is the improved paragraph broken down into its support sentences:

1. Lions are sociable animals. 2. They live in groups known as prides, where the females remain together for life and share essential knowledge with the cubs. 3. The females are responsible for hunting, teaching the cubs the boundaries of their territory, and where to find hunting grounds and water sources. 4. The male lions protect the pride, which functions like an extended family.

The four support sentences work together to provide a clear picture of lion social structure and dynamics within a pride.

Extra: Lions (Panthera leo) are known for their social structure, which is somewhat unique among the big cats. The social unit of lions, the pride, typically consists of related females, their cubs, and a small number of adult males. This structure allows for cooperative care of the young and an effective division of labor, with females usually hunting together in a coordinated fashion to take down prey.

The concept of a pride is central to understanding lions' behavior. Prides can range in size from just a few individuals to more than a dozen. Females generally remain in the pride into which they were born, creating a stable core group that can survive for many generations, passing on knowledge and hunting skills. Male lions often have to leave the pride upon reaching maturity and either become solitary or form coalitions with other males to try and take over new prides.

Males have the role of defending the pride's territory from intruders and other threats, while females are the primary hunters for the pride. This division of duties contributes to the pride's survival and success. The social nature of lions is a fascinating aspect of their ecology and one that is studied extensively by biologists and conservationists alike to understand and conserve this iconic species.
