How do wetlands abiotically to protect the water quality of a marine ecosystem?

A wetland is considered to be an ecosystem that is highly rich in flora and the water is available through out the year.

It helps in nourishing the ecosystem in a variety of ways-

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
