Question

The bottom of the Euphotic Zone is also called what?

Hint the answer is not

photic zone or aphotic zone

Answer 1

The uppermost layer of the world's oceans is bathed in sunlight during the daytime. This bright ocean layer is called the sunlit zone or the euphotic zone (euphotic means "well lit" in Greek) or the epipelagic zone (epipelagic means "upon the sea"). The depth of this zone depends on the clarity or murkiness of the water. In clear water, the euphotic zone can be quite deep; in murky water, it can be only 50 feet deep. On average, it extends to about 660 feet (200 meters); the depth of the ocean averages about 13,000 feet or 4,000 m. The temperature in this zone ranges from 104 to 27 degrees F.

In this zone, there is enough light for photosynthesis to take place, so many plants and other photosynthetic organisms live in this zone and food is abundant. Photosynthesis is a process in which sunlight and carbon dioxide gas are converted into food (chemical energy contained in carbohydrates) and oxygen gas. Photosynthesis in the oceans creates approximately 90% of the Earth's gaseous oxygen. Most of the oxygen is produced by phytoplankton. These primary producers (also called autotrophs) are the first link in the food chain in the oceans. Because of this food source, many animals also live in this zone. In fact, most of the life in the ocean is found in this zone, although it is the smallest ocean zone in terms of volume of water.

Answer 2

The Mesopelagic zone is the zone right beneath the photic/euphotic/epipelagic zone. It is about 800 metres.

The bathypelagic zone is under the mesoeplagic zone and it is about 3000 metres.

The Abyssopelagic is the last layer of the ocean (not counting the hadopelagic which occurs in really deep crevasses.).

Answer 3

Disphotic zone.
