When there is a drought a lack of rain causes the soil to become dry and because of this lack of moisture plants that depend on the moisture in the soil die. When these plants die they no longer release water into the atmosphere through transpiration. This works with other factors to decrease the humidity and therefore cloud formation. Without clouds there can be no rain. What kind of feedback is this?
Reaction and response loop. The plant is reacting to the amount of water, therefore it begins to die from there being less of it. The response from the plant dying means the answer. I'm not sure about this, but here is my answer that I would give.
