madreJ [45]
If the water is salty like in the oceans, as the water freezes the salt is pushed out making the water denser making it sink to the bottom in a current to keep climate cool and the surface currents warm the artic. The way it effects life is, it makes a passageway over the freezing water across so that you won't freeze to death swimming. And it helps migration too. The Sub-zero waters keep algae from growing, which is good because most are hibernation.

What is an invasive species?
Serga [27]

Answer:

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
