Invasive species consume limited resources and become competitor of native species in a given ecosystem

Invasive species are the outsider species introduced in any given ecosystem. These invasive species become a competitor with the native species of that ecosystem for limited resources and hence deplete the limited resources at a faster pace thereby leaving all other species at the risk of dying.
If they are decreased at the same time and the same amount is being taken away from them at the same time then the gravitational force would stay the same but if they are be decreased one then the other they will go back and forth
