Summary Introduction

To explain: The density-dependent birth rate of dune fescue grass exemplifies negative feedback.

Concept introduction: The negative feedback is a type of feedback regulation, where the counteraction of an outcome takes place by its own influence on the process. As when a level of a particular entity is increased than it may inhibit by its own growth. So, it is a process that regulates biological systems.

The birth rate of “dune fescue grass”, which is “density-dependent”, is regulated by negative feedback mechanism.
