Final answer:
Hunting larger prey can put a lion at a higher risk of injury. A failed hunt increases a lion's energy costs.
Step-by-step explanation:
When a lion hunts larger prey, there are negative consequences it may encounter. One of these consequences is an increased risk of injury. Hunting larger prey like buffalo or giraffes can be more dangerous as they have the ability to defend themselves and can inflict serious injuries on the lion.
If a lion fails to hunt, its energy costs increase. Hunting requires a lot of energy, and a failed hunt means wasted energy. The lion would need to spend more energy to hunt again, increasing its energy expenditure.
