Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.
