Feedback Loops

Front

What is a negative feedback loop?

Back

A process that counteracts changes, helping to maintain stability by decreasing the effect of an action.

Front

What is a positive feedback loop?

Back

A process that amplifies changes, leading to an increase in the effect of an action.

In a negative feedback loop, each action creates a consequence that _____________________ the other action.

What is an example of a negative feedback loop in the human body?

Back

Regulation of body temperature through sweating or shivering.

Front

What is an example of a positive feedback loop in nature?

Back

The melting of permafrost releasing methane, which enhances the greenhouse effect.

Front

How do negative feedback loops help maintain homeostasis?

Back

They prevent small changes from getting larger, stabilizing the system.

Front

How do positive feedback loops affect systems?

Back

They can lead to rapid changes and potentially destabilize the system.

Front

What role do feedback loops play in ecological systems?

Back

They regulate population dynamics and resource availability.

Front

What is the greenhouse effect?

Back

The warming of Earth due to trapped heat from greenhouse gases.
