Answer:
Option (A)
Explanation:
Upwelling usually refers to the rising up of denser, deep-sea cold water to the surface of the ocean, replacing the less dense warm air.
It takes place both near the coastal areas and in the broad open ocean.
The deeper cold water is highly rich in the valuable nutrients, and as they rise up they carry these nutrients and distribute them in the upper region of the ocean water body. The marine organisms are directly dependent on these nutrients, thereby helps in biological productivity.
Thus, the intense upwelling occurring in a particular area in the ocean signifies the abundance of marine species.
Hence, the correct answer is option (A).
During cellular respiration, OXYGEN serves as an electron acceptor and Adenosine triphosphate (ATP) is produced. during photosynthesis, WATER serves as an electron donor and oxygen molecules, hydrogen ions and electrons are produced.
