Answer:
The graph illustrating such a phenomenon will show a sharp curve in upward manners in the beginning but then will grow downwards as the predation increases.
Explanation:
When a rabbit population is introduced in a habitat, the new habitat will have abundant food for the rabbits. As a result, the population of the rabbits will grow at a much faster rate and hence the graph will move sharply upwards in the beginning. But with the passage of time, the predators of the rabbits will also increase due to the abundance of their preys. More predators will feed on more rabbits and hence a slow decline in the curve will be seen afterwards.
