DIRECTIONS: The following items consists o f two statements, Statement...
The Grand Banks is a large area of submerged highlands southeast of Newfoundland and east of the Laurentian Channel on the North American continental shelf. It is in this area that the cold Labrador Current mixes with the warm waters of the Gulf Stream. The mixing of these waters and the shape of the ocean bottom lifts nutrients to the surface. These conditions created one of the richest fishing grounds in the world. Plankton are organisms that live in the water. They are carried by waves, tides and currents. They are usually found in the shallow surface waters.

DIRECTIONS: The following items consists o f two statements, Statement...
Statement I: Grand Banks are one of the major fishing grounds of the world due to the presence of a vast continental shelf
Statement II: Planktons grow in the shallow waters.
The correct answer is option 'B', which states that both statements are individually true, but Statement II is not the correct explanation of Statement I.
Explanation:
Statement I: Grand Banks are one of the major fishing grounds of the world due to the presence of a vast continental shelf
The Grand Banks is an area of the North Atlantic Ocean where the sea floor slopes gently from the edge of the continental shelf. This area is known for its rich fishing grounds and has been a major fishing area for centuries. The presence of a vast continental shelf is one of the factors that make the Grand Banks a productive fishing ground.
The continental shelf is the shallow, submerged extension of a continent. It is typically rich in nutrients and supports a diverse ecosystem, including fish and other marine organisms. The presence of a vast continental shelf in the Grand Banks provides ample habitat for fish and other marine life, making it an attractive fishing ground.
Statement II: Planktons grow in the shallow waters.
Plankton refers to a diverse group of organisms that drift in the water column, including microscopic plants (phytoplankton) and animals (zooplankton). While it is true that plankton can be found in shallow waters, they are not exclusively limited to this habitat. Plankton can be found in various depths of the ocean, including the open ocean and deeper waters.
Plankton are primary producers and form the base of the marine food chain. They are an essential food source for many marine organisms, including fish. Therefore, the presence of plankton is important for the productivity of fishing grounds.
Conclusion:
Both Statement I and Statement II are individually true. The Grand Banks are indeed one of the major fishing grounds of the world due to the presence of a vast continental shelf. Plankton do grow in shallow waters, but they are not exclusively limited to this habitat. Therefore, Statement II is not the correct explanation of Statement I. The productivity of the Grand Banks as a fishing ground is influenced by various factors, including the presence of plankton, but it cannot be solely attributed to plankton growing in shallow waters.
