Aphotic, euphotic and disphotic

Euphotic, disphotic and aphotic
The photic zone or euphotic zone is the depth of the water in a lake or ocean, that is exposed to such intensity of light at which the rate of oxygen consumption, is equal to the rate of carbon dioxide production. It extends from the surface down to a depth where light intensity falls to one percent of that at the surface, called the euphotic depth. About 90% of all marine life lives in the euphotic zone.
Benthos of pond ecosystem are
-
Producers
-
Primary consumers
-
Secondary consumers
-
Tertiary consumers
Benthos are the organisms found at the bottom of freshwater bodies such as lakes, rivers, and streams and since light cannot reach such deep water, therefore, they depend upon organic matter. This dead and decaying matter sustain their food chain hence, they are mostly scavengers or detritivores, belonging to primary consumers of detritus food chain.
Organisms living at the bottom of a lake are
-
Nekton
-
Benthos
-
Plankton
-
Pelagic
Abyssal zone in ocean has
-
No sunlight but contains consumers and decomposers
-

Aphotic zone in deep water
-
Euphotic zone in open water
-
Disphotic zone in deep water
-
Dark bottom of deep water body
Benthoic animals lives
-
Deep in sea
-

Active swimmers
Which of the following supports a dense population of plankton and littoral vegetation?
-
Oligotrophic condition
-
Eutrophic condition
-
Lithotrophic condition
-
Agroecotrophic condition
Ponds and lakes are stationary fresh water ecosystems. Ponds are generally shallower with depth less than 2 meters. Shallow lakes are eutrophic with rich biota and quick circulation of nutrients. Producers in a pond or lake ecosystem include phytoplanktons like diatoms, desmids, Chlorella, Chlamydomonas, Spirogyra, Chlamydomonas, Oedogonium etc. Littoral zones occur on the edge of large lakes and rivers, having dense growth of vegetation. Therefore, the correct answer is option B.
Littoral zone is found along
-
High mountain
-
Sea
-
River
-
Desert
1) The zone at the edge of a lake or sea or in an aquatic habitat which is alternatively exposed to air is called 'Littoral zone'.
