1. Meeting point of warm and cold ocean currents.
2. Gentle continental shelves.
3. Abundance of planktons.
Select the correct answer using the code given below.
The correct option is D (d) All of the above
Statement 1 is correct - a Laurentian type of climate is found only in two regions- One in North eastern
North America wherein warm Gulf Stream meets with cold Labrador currents and second in Eastern coast of Asia where warm Kuroshio meets with cold Oyashio currents. The fusion of currents is most favorable condition for fishes to grow.
Statement 2 is correct as continental shelves in these regions are gentle. Fish feeds like planktons grow in shallow waters adjacent to land mass. Planktons are photosynthesizing microscopic organisms that inhabit the upper sunlit layer. In shallow water, they can access sunlight easily.
Statement 3 is correct- as explained above planktons are an important feed of fish and shares a direct relation with abundances of planktons.
