Explanation:
1. Since the Lions are the predator and Gazelles are the prey therefore a predator-prey relationship exists between them. The predator-prey relation is also associated with the food chain in an ecosystem. If the number of prey is reduced then there are chances that the number of a predator will also be reduced but
2. The Lion is not just the predator of Gazelle but other animals also like deer therefore they can shift their resource of food from gazelles to another organism.
3.The change of the ecosystem will change the population of the predator as the population are adapted to grow in a particular ecosystem and change of population could reduce the population of a predator.
The independent variable is the plant growth or how much the plants grow.
