Answer:
Invasive species consume limited resources and become competitor of native species in a given ecosystem
Explanation:
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.
Most organisms can tolerate a very narrow pH range close to neutral, i.e., around pH 7. It is likely that there would not be much life in the lake at pH 3. Once the pH increases to above 5.5 to 6, it is more likely that life would begin to survive. Once the pH rises to above around 9, the solution is starting to become basic, and once again, few organisms will survive.
