Answer:
Option (C)
Explanation:
A barrier island is usually defined as a long and narrow type of land that is dominantly comprised of sand particles and are oriented parallel to the coastal mainland.
The presence of a barrier island protects the coastal rocks from getting eroded by the strong water waves, wind, and tidal effects. This acts as a barrier and there lies a lagoon between the coastal landform and the barrier island.
It plays an important role in the ecosystem as it provides valuable nutrients and minerals, supporting a large number of living species.
Thus, the correct answer is option (C).
Gravel in the soil helps crops grow better, since they provide nutrients. Sand however, doesn't impact the crops growth at all.
