The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration. Because of the lack of oxygen in the profundal zone during many parts of the year, fish populations are typically lower. This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly. Limnology divides lakes into three zones: the littoral zone, a sloped area close to land; the photic or open-water zone, where sunlight is abundant; and the deep-water profundal or benthic zone, where little sunlight can reach. The fauna are heterotrophs, meaning that they eat dead organisms and use oxygen for cellular respiration.

[2] The profundal zone is often part of the aphotic zone. The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration. Since it is the primary habitat for planktonic animals, the limnetic zone is the most photosynthetically active lake zone. Because light does not penetrate into it, photosynthesis does not occur there, so the food web of the profundal zone is based on materials that fall from farther up in the water column. How to say profundal zone in sign language?

Profundal Zone lies below the depth of effective light and beneath the thermocline where aquatic life is influenced by oxygen and temperature. A Dictionary of Ecology Biomes are different because of their differing latitude, climate, weather, amount of sunlight, and precipitation. The frequency data is extracted from the English Wikipedia corpus, and updated regularly. Benthic organisms reach their greatest biodiversity and number in the littoral zone (i.e. [7], Nutrient fluxes in the profundal zone are primarily driven by release from the benthos. With increasing productivity, the littoral zone may loose its heterogeneity that results in a single pro-fundal biomass maximum of the zoobenthos. The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration.This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly.

For example, rather than seaching for "sahara desert", you could instead just try "desert" first. [3] The profundal macrofauna is therefore characterized by physiological and behavioural adaptations to low oxygen concentration. Temperature: As the depth of the pond increases, the temperature of the water gradually decreases due to the gradual decrease in the light penetration.
