Why might ecologists be concerned when new invasive species arrive in an ecosystem?

Ecologists are deeply concerned when there are invasive species in an ecosystem because they have the ability to colonize that particular ecosystem, disrupting its normal routine or functions. These species may arrive naturally through migration but human activity actually poses the greatest threat in bringing invasive species into different locations.

Fiesta28 [93]

Answer:

Your answer is growth industry

I hope this helps

Explanation:

In the late 1800s, people in many parts of the world decided to leave their homes and immigrate to the United States. Fleeing crop failure, land and job shortages, rising taxes, and famine, many came to the U. S. because it was perceived as the land of economic opportunity. Others came seeking personal freedom or relief from political and religious persecution. With hope for a brighter future, nearly 12 million immigrants arrived in the United States between 1870 and 1900. During the 1870s and 1880s, the vast majority of these people were from Germany, Ireland, and England--the principal sources of immigration before the Civil War. That would change drastically in the next three decades.
