Question 3 • 2025-2026_MDCPS_2000315_Biology_1_B-CR

What adaptation do the roots of mangroves have that make them well-adapted to life in the wetlands?

Answer
A
Their roots are long enough to reach the deepest areas past the continental shelf.
B
Their roots rest loosely in the soil so the fast currents will pull them up and allow them to float.
C
Their roots are near the surface, where they have access to oxygen.
D
Their roots can survive in salt or fresh water.

Explanation

Wetland soil is often waterlogged, so little oxygen is available below the surface. Mangrove roots grow near the surface, where they can take in oxygen from the air. This makes C, “Their roots are near the surface, where they have access to oxygen,” the best answer.
