Answer to Question 1

A feedback loop is an output from a system that influences its own operations. A negative feedback loop discourages change in the system. An example is predator/prey relationships in which predators keep prey population in check. A positive feedback loop encourages change in the system. An example is warming temperatures that cause reduction in ice and snow cover and, thereby, decrease albedo and increase absorption, leading to more warming.
