What are negative feedback loops in nature?

What are negative feedback loops in nature?

Negative feedback loops are processes that counteract changes in a system, helping to maintain stability. For example, in ecosystems, when a population exceeds its resources, it may lead to a decrease in that population due to starvation, which then allows resources to recover.

Can you give me an example of a negative feedback loop?

Sure! A classic example is the regulation of body temperature in humans. When body temperature rises, mechanisms like sweating are activated to cool the body down, restoring it to a normal temperature.

How do these loops affect ecosystems?

They play a crucial role in maintaining balance. For instance, if predator populations increase, they may reduce prey populations, which in turn can lead to a decrease in predator numbers, allowing prey populations to recover.

Are there positive feedback loops as well?

Yes, positive feedback loops amplify changes. For example, in climate change, melting ice reduces the Earth's albedo, leading to more heat absorption and further ice melt.
