Question

question 6
which of the following best describes a positive feedback loop in environmental systems?
output from a system remains constant regardless of changes in input, maintaining the system in equilibrium.
increased output from a system leads to further increased input, driving the system further toward an extreme.
increased output from a system leads to decreased input, stabilizing the system.
input and output from a system remain constant, resulting in no change in the system.
increased output from a system leads to decreased input, resulting in a gradual decline in the systems stability.

Explanation:

In a positive - feedback loop, an initial change in a system causes a response that amplifies the original change. When increased output from a system leads to further increased input, it drives the system further toward an extreme, which is the characteristic of a positive - feedback loop. The other options describe equilibrium, negative - feedback loops, or stability - maintaining mechanisms.

Answer:

Increased output from a system leads to further increased input, driving the system further toward an extreme.
