Explanation:

There are four main stages of invasion i.e. introduction, naturalization, colonization, and dispersal or spreading. In the first stage, the specie is introduced in the environment, in the second stage the specie adopt the environment, in the third stage the specie started growth and make colonies to increase its population and in the last stage the specie disperse in the environment through different means and spreading of that organism occur. The failing of adaptation to the environmental conditions leads to the failing of invasion of a specie.
