Q. With reference to “Kelp Forest” consider the following statements:
1.Kelps are extremely large brown algae.
2.Kelp forests are always coastal.
3.They overlap with coral reefs and mangrove forests.
Which of the statements given above is/are correct?

[A] 1 and 2 only

[B] 2 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A

Statement 1 and 2 are correct. Kelp forests thrives in cold, nutrient-rich waters. Kelp are not plants, but rather extremely large brown algae, and many different species of kelp make up kelp forests. Kelp forests are always coastal and require shallow, relatively clear water.

Statement 3 is incorrect.  Kelps live further from the tropics than coral reefs, mangrove forests, and warm-water seagrass beds, so kelp forests do not overlap with these systems. However, like those systems, kelp forests provide important underwater habitat.
