Here's why:
* Equilibrium implies a state of balance where opposing forces are equal. In an ecosystem, this means that birth rates and death rates, along with immigration and emigration, are relatively balanced, leading to a stable population size.
* Dynamic equilibrium emphasizes that this balance is not static. It's a constantly shifting balance, with populations fluctuating within a certain range.
However, it's important to remember that ecosystems are complex and rarely perfectly balanced. There are always natural fluctuations, and disturbances like fires, droughts, or invasive species can disrupt equilibrium.
So, while the term "equilibrium" is used to describe the general stability of an ecosystem, it's not a perfect description of the reality of a constantly changing environment.
