From Wikipedia, the free encyclopedia
This article has a lot of good information and descriptions. The topic is very interesting and the article provides a lot of discussion of the animals that live in the aphotic zone and the other parts of the ocean. The introduction is a bit confusing and there is a limited description of what the aphotic zone actually is. There are also some spelling mistakes and little details that need to be cleaned up as well as making it flow better as it is hard to follow the train of thought in this article. Some more descriptions in the introduction could help this flow better as well as breaking it up into sections to have a structure of topics and characteristics that make the aphotic zone unique. Overall, this article has a lot of good information and explains why this topic is so unique, but it doesn’t flow very easily and could be improved with some structural changes as well as an improved introduction.
The aphotic zone (aphotic from Greek prefix ἀ- + φῶς "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1 percent of sunlight penetrates. Above the aphotic zone is the photic zone, which consists of the euphotic zone and the disphotic zone. The euphotic zone is the layer of water in which there is enough light for net photosynthesis to occur. The disphotic zone, also known as the twilight zone, is the layer of water with enough light for predators to see but not enough for the rate of photosynthesis to be greater than the rate of respiration.
The depth at which less than one percent of sunlight reaches begins the aphotic zone. While most of the ocean’s biomass lives in the photic zone, the majority of the ocean’s water lies in the aphotic zone. Bioluminescence is more abundant than sunlight in this zone. Most food in this zone comes from dead organisms sinking to the bottom of the lake or ocean from overlying waters.
The depth of the aphotic zone can be greatly affected by such things as turbidity and the season of the year. The aphotic zone underlies the photic zone, which is that portion of a lake or ocean directly affected by sunlight.
