Negative Feedback Loops

Definition

Negative feedback loops are regulatory mechanisms within ecosystems that work to maintain balance by reducing or reversing any changes that occur. They help stabilize and restore equilibrium.

Analogy

Think of negative feedback loops as a thermostat for your home. When the temperature rises above the desired level, the air conditioner turns on and cools down the room. Once it reaches the desired temperature, it turns off until it's needed again.

Trophic Interactions: Trophic interactions describe feeding relationships between organisms within an ecosystem and how energy flows through them.

Positive Feedback Loops: In contrast to negative feedback loops, positive feedback loops amplify changes within ecosystems rather than maintaining balance. They can lead to rapid and sometimes unpredictable shifts in ecological systems.

Homeostasis: Homeostasis refers to the ability of an organism or system to maintain internal stability despite external changes. It is similar to negative feedback loops as both aim for stability and balance.
