Claim: The drought caused the lions' home range and movement patterns to change.
Evidence: During a drought, water and food resources become scarce, and this affects the prey animals that lions depend on. In response, the prey animals change their movement patterns to seek out water and food, and this causes the lions to also change their movement patterns to follow their prey. As a result, the lions' home range shifts to areas where the prey is more abundant.
Reasoning: Lions are apex predators and their survival depends on their ability to find and catch prey. During a drought, when water and food become scarce, the prey animals change their behavior and move to areas where they can find resources. The lions, in turn, must also change their behavior to keep up with their prey and ensure their own survival. This means that the lions' home range and movement patterns will shift to follow the prey. Therefore, the drought causes the lions' home range and movement patterns to change.
