The correct answer is - accident.

In general, the invasive species are introduced into a new environment accidentally.This means that they have not been introduced on purpose, or in order to cause any harm to the ecosystem, though there are some exceptions.

The invasive species are usually very dangerous to the local ecosystem. The reason for that is that they usually do not have predators in the new ecosystem, or if they are the predators, than the local flora and fauna do not have defense mechanisms to cope with it. They also act very aggressively, have more offspring, as well as having the offspring on much shorter periods of time, which ends in occupying the space of the local organisms and even leading to their extinction.

Identify an organism that is present in your local ecosystem, and discuss two limiting factors that may affect this organism.

Verdich [7]

Limiting factors of an ecosystem include disease, severe climate and weather changes, predator-prey relationships, commercial development, environmental pollution and more. An excess or depletion of any one of these limiting factors can degrade and even destroy a habitat.

Evolution creates not the best solution but the most available. Building on your answer to the previous question what does this

Greeley [361]

This statement means that evolution has happened by getting the genes of the right trait expressed at the right time to help adaptability.

Explanation:

Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.

We can conclude that all features are not adaptable some are the results of genetic drift or mutations.

In case of cheetah, the faster running genes would have been there they got expressed over the period of time for better adaptability.
