The answer is Lionfish
are native to the tropical Pacific. There are no natural water routes of warm
water between the Pacific and Atlantic oceans.
Invasive species is a species that colonizes an environment
in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally
found in the indo-pacific, which is their
native environment. However, their presence
in the eastern United States has have threatened
the ecosystem of the region. The fish has decimated fisheries and reef
ecosystem since they also don’t have natural predators in the region. Therefore,
their population explodes unchecked.
If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
The process of where organisms with favorable traits that help them adapt to an environment are more likely to reproduce and survive. Organisms with less favorable traits are less likely to survive in the environment. This theory was first developed by Charles Darwin and has grown to be the most believed process of evolution.
