When something is "dynamic" it is not in equilibrium.
So you don't believe in dynamic equilibrium? Here's something for you to consider:
Ecologists often study the relationships between multiple species and their effects on each other. One relationship in nature that often shows dynamic equilibrium
is the predatory-prey dynamic. Imagine a nature reserve that only contains rabbits and wolves. As the rabbit population increases, it provides more food for the wolf population. This sets both populations into dynamic equilibrium
. The wolves, reaping the benefits of the increased rabbit population, also start to reproduce more. After a period of time, the wolf population also starts to increase dramatically. As more wolves are born and eat the rabbits, their populations eventually level off. The wolves, still reproducing at high levels, eventually start decreasing the rabbit population, which cannot keep up. The rabbits decrease, and eventually the wolves are left without enough food to support a large population. This dynamic equilibrium
of both populations is interesting because it shows a direct cause and effect relationship between different species in an ecosystem.
