Answer:
B. They filter salt from the water using their roots.
These trees have adapted to saltwater and play a significant role in the environment. Mangrove trees protect the coasts against erosion caused by waves, winds, and tides. They also protect coral reefs and seagrass beds from silting or deposition of sand. They are also breeding grounds for different varieties of fish and shellfish. Other organisms found in the mangrove ecosystems are algae, oysters, shrimps, lobsters, and crabs.
