Front

What is a positive feedback loop?

Back

A positive feedback loop is a process that amplifies the effects of a change, leading to an extreme outcome.

Give an example of a negative feedback loop in the human body.

Back

Maintaining body temperature is an example of a negative feedback loop.

Front

What happens in a negative feedback loop?

Back

In a negative feedback loop, the system works to counteract changes, promoting stability.

Front

What happens in a positive feedback loop?

Back

In a positive feedback loop, the system enhances changes, leading to a greater deviation from the norm.

Front

How do negative feedback loops contribute to homeostasis?

Back

Negative feedback loops help maintain homeostasis by counteracting changes in the body, such as temperature regulation.

Front

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

Back

An example of a positive feedback loop is the process of childbirth, where contractions lead to more contractions.

Front

What is the role of feedback loops in ecosystems?

Back

Feedback loops in ecosystems help regulate populations and maintain balance within the environment.

How can positive feedback loops lead to a 'vicious circle'?

Back

Positive feedback loops can lead to a 'vicious circle' by causing a cycle of worsening conditions, such as poverty leading to illness.
