Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.

The way in which consumers<u> </u><u>most benefit </u>from a perfectly competitive undifferentiated market compared to a monopolist competition is that this kind of market will produce lower prices.
An increase in the<u> number of choices</u> as well as the<u> amount of marketing</u> can be considered consumer benefits of a perfectly competitive market in that the increased competition will force companies to expand into new products and invest more towards marketing in an effort to attract consumers, thus making it easier for said consumers to find their desired product.
on the other hand, a monopoly is when a <u>single controlling entity </u>has ownership of<u> all or almost all of the producing companies for a specific product</u>, causing an absence of competition and thus eliminating the need for competitive pricing. Though the benefits mentioned before are good for consumers, the greatest benefit is in the reduction in prices caused by a competitive market, allowing much greater access to a wider variety of goods for all of the economic classes.
