Most plantonic life in the ocean exists in an area that is very vulnerable to marine pollution. This area is called the nutrient-rich zone.
Answer: Option D
<u>Explanation:</u>
Most plantonic life in the ocean exists in the nutrient rich zone of the ocean. Sunlight is essentially the ultimate resource for the photosynthesis of these planktons. The photosynthesis is largely restricted to the upper layer.
Hence they are in the surface where the light penetration is available. This surface area is so rich in nutrients and hence called as the nutrient rich zone. The surface area is always active producing gases. The marine organisms biogenic sediments are all concentrated on the surface layer.
During volcanic eruptions, some of those that is emitted by the volcano are water vapors. With the proper conditions, these water vapors then condense. The precipitation of water vapors from volcanic eruption about 3-4 billion years ago became the origin of the seas.
It would be B because if people were to enter another country from their homeland, they could only increase the population of their new land when barring children.
Actually the answer on this question would be:
“reactor coolant”
The reactor coolant mostly used is simply sea water, or
water could be. The role of the reactor coolant is simply to cool the reactor.
It does not come into contact with any radioactive source since it only cools
the reactor from the outside, it acts like a jacket of coolant.
