When a species is moved from its native area to a new area, it can become an invasive species and damage its new ecosystem. What is one reason these species are able to do damage to an ecosystem? a. When moved to the new location, the species fills in unoccupied niches.
b. Having been moved from its home country, the introduced species does not know the local language so is unable to communicate with its new neighbors and gets angry, lashing out at any nearby organisms and doing great harm.
c. When a species is transported, it leaves behind its predators and the diseases that previously kept its population in check. Therefore the species is able to grow to large and damaging numbers.
d. In nearly every case, when a species is moved across an ocean and into a new habitat it becomes a harmful invasive species simply because it is in a new habitat.

c. When a species is transported, it leaves behind its predators and the diseases that previously kept its population in check. Therefore the species is able to grow to large and damaging numbers.

Explanation:

An invasive species is the species that is not native to the ecosystem in which that species has entered. Invasive species are responsible for the destruction of the ecosystem because they outcompete with native species and reproduce faster than them.

This happens because in the new ecosystem they do not have their natural predators which control their number and not the pathogens that cause disease in them. Therefore they grow exponentially and outcompete native species.
