What is one of the most effective ways to stop invasive animal species from entering the great lakes ecosystem? a) gl environmental research laboratory hopes to minimize the economic impacts of species invasions by developing effective chemical biocides. b) gl aquatic non-indigenous species information system (glansis) provides extensive invasive species collection records for the great lakes region. c) gl inspectors assess the ballasts of boats to prevent and stop the inflow of invasive species in to the great lakes region d) gl agents will educate boaters, resource managers, and the general public that include accurate information on the threat of invasive species.

The correct answer is option C, that is, GL Inspectors assess the ballasts of boats to help prevent and stop the inflow of invasive species into the Great Lakes region.  

A plant or animal, which is not native to an ecosystem is known as an invasive species. During the last two centuries, the invasive species have substantially modified the ecosystem of the Great Lakes.  

It has been reported that about 30 percent of the invasive species in the Great Lakes have been presented via ship's ballast water. Thus, there is a need to access the ballasts from the boats to assist in stopping and preventing the inflow of invasive species to the Great Lakes region.  

Option (C)

Explanation:

Invasive species are usually defined as those species that are completely new to an ecosystem. They are not the native species, and the presence of these species can lead to a reduction in the native species and also there will be a reduction of food, loss of habitat and disturbances in the food chain. For example, Asian Carp, Zebra Mussels, Domestic cats and many others.

One of the most effective way by which these invasive species can be stopped from entering the ecosystem of Great Lakes is by evaluating the ballasts of the large ships and propellers of the smaller boats, through which these species are carried from one type of ecosystem to another. by evaluating and monitoring these ballasts properly, the inflow of these species can be stopped.

Thus, the correct answer is option (C).

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
