Classify each of these examples as a negative or a positive feedback loop and explain why.ScenarioNegative or positive feedback loop?ExplanationThe population of rabbits on an island increases. This causes the number of feral cats to increase because they have more food. As more rabbits are eaten, their population decreases again.
Solution
This scenario is an example of a negative feedback loop. In a negative feedback loop, the system responds in a way that counteracts the initial change, bringing the system back to its original state. In this case, the increase in the rabbit population leads to an increase in the feral cat population (since they have more food). However, as the cats eat more rabbits, the rabbit population decreases again, counteracting the initial increase. This brings the system back to its original state, hence it's a negative feedback loop.
