    ANSWER :

    1. On a coastal bluff, plant growth inhibits erosion, which allows for more stabilizing plants to grow on the bluff : Negative Feedback Loops

    2. As agriculture intensifies, more humans can obtain food, which increases the global population, requiring more agricultural output : Positive Feedback Loops.

    EXPLANATION:

    1. Negative feedback loops defined as minimize change within the system to keep a system in equilibrium.

    Example :

    When we push a ball up a hill and when we stop pushing it, it will again return to the bottom. Therefore, system recovers.

    According to the question...

    On a coastal bluff, plant growth inhibits erosion, which allows for more stabilizing plants to grow on the bluff : Minimises effect for more stabilizing plants to grow on the bluff.

    2. Positive feedback loops is defined as that enhance an initial effect in the system that can be disruptive or detrimental to a system

    Example:

    When we roll ball down a hill, then ball goes faster as it goes down the hill which means it enhance an initial effect.

    According to the question...

    As agriculture intensifies, more humans can obtain food, which increases the global population, requiring more agricultural output: It enhances the initial effect which intensifying agriculture, feed more population and this need more agriculture.
