D. The species isn’t a part of the ecosystem.

In the given question both Option A and Option B are correct i.e. either a native species has changed its range or an invasive species has been introduced into the area.

How native species changed its range?

A species range is an area where a particular species can be found during a lifetime.

Species range include area where a specie sustain or migrate or breed and hibernate.

Different species has different unique geographical range.

Species with range covering different forest cover are called as cosmopolitan distribution.

Factors important for range determination:

- Climate

- Availability of food material

- Availability of Water

- Type of topography

What are invasive species?

An invasive species are the organisms that either introduced intentionally or accidentally but later harm the endemic species by affecting their habitat and bioregions leading to ecological and economical damages.

Invasive species are the fast growing species which survive on the given nutrients which are available to the endemic species and in competition beats the existing species and slowly and steadily these invasive species cover the entire region resulting into change in the ecology of the region.

Invasive species shows the classic example of theory of natural selection and survival of the fittest.
