The opportunistic has a longer lifespan than the equilibrium populations

Opportunistic Traits

Explanation:

Characteristics:  K-strategy; Carrying Capacity of environment; few offspring; usually brood them or take care of them in another way; grows fast until it takes up all the space; prefers a stable environment; long life; most birds and mammals and some live birthing fish like dogfish.

In an opportunistic population, growth pattern is exponential.The populations are regulated by density-independent factors. Organisms produce plenty of gametes because the chance for fertilization is very low. The examples of the opportunistic population are insects, corals, oysters, etc.

In an equilibrium population, growth pattern is logical. The populations remain near carrying capacity. Organisms have much fewer offspring and take care of them. The examples of the equilibrium population are birds, mammals, and some fish.

Opportunistic species use what is called an R-strategy. By producing dozens of eggs and sperm they increase the chance of fertilization, species who perform to this are commonly first to colonize new environments with a with a short life cycle but large population. Once resources become scarce as they are consumed, the species often dies. Insects, corals, clams etc or other water spawning animals are good examples.

Equilibrium species use what's called a K-strategy. Such species often produce less offspring and nurture them more, the preference for such species is a stable environment. Mammals and large live-bearing species are the best examples of this.
