Which concept is illustrated when agricultural technology raises output and is followed by population and land pressure?
Answer and explanation
Correct answer: Positive feedback loop
A positive feedback loop occurs when an initial change produces effects that reinforce the same direction of change. Higher agricultural output may support population growth and greater demand for food, which can encourage further cultivation, irrigation and land conversion. The process may have complex limits and is not automatically beneficial, but the reinforcing relationship described is positive feedback. Thus B is correct.
