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.

Explanation:

Mangrove trees have dense, tangled root systems that anchor coastal soil, preventing erosion from tides and storms, which is a core well-documented benefit they provide to coastal wetlands. While they offer other water-related benefits, soil stabilization is a primary, defining ecological role of mangroves for these habitats.

Answer:

A. They hold soil in place.
