"These creatures too need oxygen and the low pressure area / cyclone is the best source to mix oxygen in the oceanic water so that the biological life survives, maintains itself and progresses in future.
"In any ocean, if there is a cyclone, it enhances biological productivity of the basic food material (phytoplankton and zoo-plankton) for the survival and growth of the fishes.
"We wish to eat fish but we must realize that even fish needs to eat its own food. If there are no cyclones, ocean will become dead ocean /sea.
"The second aspect is that the churning of water provided by the cyclonic winds, helps to clean the oceanic water so that the sunlight can penetrate deeper into the water to create a higher production of basic food material in the ocean itself.
"The third point is that a cyclone uproots older trees giving path for a relatively a new crop of younger trees in nature.
