A lion's niche refers to its place in its ecosystem and the lion's niche is at the top of the food chain where it is responsible for eating numerous animal species. The lion's job in its ecosystem is to help control the population of other animals in the ecosystem by hunting and eating them.
The lion hunts and eats impalas, wildebeest, gazelles and zebras as well as smaller animals. The female lions typically do most of the hunting because they are smaller and do not have the huge mane that the male lions have. Most lions hunt in groups, but they can and will hunt alone when it is necessary. When the lions are not hunting, they tend to sleep. Lions will spend as many as 20 hours each day sleeping.
The lions are able to attack their prey with retractable claws and their sharp teeth. They don't have to worry about animals struggling and fighting back because they have loose skin around their abdomen to protect their stomach. They also have tongues that are able to quickly remove flesh from the bone. Most lions live within the grasslands and wooded areas of southern Africa. Unfortunately, despite the lion's importance to its ecosystem, the lion is considered "vulnerable" by the International Union for Conservation of Nature due to habitat destruction.
