Question

which is one benefit that mangrove trees provide to surrounding coastal wetlands?

• they hold soil in place.
• they store floodwaters.
• they maintain surface water flow.
• they filter water and improve water quality.

Explanation:

Mangrove trees have extensive root systems that help stabilize the soil in coastal wetlands, preventing erosion. Storing floodwaters is not a primary benefit of mangroves. Maintaining surface water flow is not a key role, and while they can filter to some extent, holding soil in place is a well - known major benefit.

Answer:

A. They hold soil in place.
