Seagrass beds provide many benefits to the near-shore ecosystem, such as providing oxygen, stabilizing sediment, creating nursery grounds for many marine species, and acting as a food source for sea turtles and manatees. this unique habitat is diminishing in locations with increased coastline development and boating activity. which type of regulation can best protect seagrass-bed habitat?

control populations of manatees and sea turtles.
fence in seagrass areas so they will not be overexploited.
limit or ban motorized boats in critical seagrass communities.
require developers to install seawalls when building near the coast.

C

Explanation:

By limiting or banning motorized boats in critical seagrass communities the populations of manatees and sea turtles would have a chance to recover from stress and mechanical injuries caused by motorized boats. Also the seagrass would have a chance to recover from pollution and other impacts that the tourists generate during their recreational activities.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
