Answer

Brief Explanations:

Positive - feedback mechanisms amplify changes in a system rather than reduce them. They can occur naturally (e.g., melting ice - albedo feedback in climate) or due to human activity (e.g., deforestation - climate change feedback). They lead to increased change as the output of a system further stimulates the system.

Answer:

D. Positive feedback mechanisms reduce change in a system
