51. What is the importance of the photic zone in aquatic habitats? a. Oxygen levels are very low in the photic zone, often resul
ting in mass mortalities. b. Only plants can thrive in the photic zone. c. Habitats that have a large photic zone are more likely to have a high level of nutrients d. Predation is lowest in the photic zone e. The photic zone is where most primary production occurs
Answer: e. The photic zone is where most primary production occurs.
Explanation:
The photic zone can be define as the sunlight or photosynthetic zone. It is the uppermost layer of the water body like lake, ocean, pond or others. This zone receives the maximum sunlight in the entire water body. Thus this facilitates the growth of large number of plants and other autotrophs like diatoms. This is called as the zone of primary productivity because in water the sunlight and dissolved atmospheric carbon dioxide are available for conducting the process of photosynthesis.
The photic zone is where most primary production occurs
Explanation:
A photic zone is a zone where net primary productivity occurs as a result of being the top and uppermost layer of the water surface these zones have an oxygen-rich environment for the thriving populations fish and large.
It Also varies with seasons and thickness changes from time to time it is the home to 90% of the marine life and also is called the disphotic zone it coincides with the epipelagic zone.
Transparency of water is an important property of this zone.
By doing my research on on this question, it look likes this war was settled in the <span>seventh-century. They named it the "Arabian War". They considered very severe and intense to be in this war. </span><span> Hope this helps</span>
