profundal zone - English definition, grammar, pronunciation, synonyms profundal zone . As the body of water ages, this zone will increase. The difference between the littoral zone and the profundal zone is that the profundal zone does not have light that reaches it and it is under the limnetic zone, but both have a bottom sediment benthic zone where decomposition is common. A variety of freshwater fish also occupy this zone. They protect coastlines from erosion. The different types of animals and plants in a pond ecosystem will interact with each other and the surrounding environment thereby forming an ecosystem. a student notices that her guppies reproduce most when her fish tank water is slightly alkaline. Login . A lake ecosystem or lacustrine ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (non-living) physical and chemical interactions. The littoral zone in an aquatic ecosystem (river, lake, sea) can be defined by the presence of sunlight at the sediment level, and the corresponding growth of partially-submerged to fully-submerged aquatic plants. "zone-to-zone travel" in Chinese: Examples The zone in a lake or pond between the littoral and profundal zones , extending from the edge of the area occupied by rooted plants to a depth of about six to ten meters , where the water temperature declines [8] The anoxic nature of the profundal zone drives ammonia release from benthic sediment.

Below the depth of effective light, beneath the thermocline, lie the profundal waters. [3] The profundal macrofauna is therefore characterized by physiological and behavioural adaptations to low oxygen concentration. The size of this zone is determined by the pond or lake's age and water clarity. The topmost zone located near the shores forming the boundary of the lake is a shallow zone termed as the littoral zone. they stop reproducing if the water becomes acidic or if the water becomes too alkaline.

What animals live in the profundal zone? - Answers The benthic zone is a community of organisms that thrive in, on, or near the seabed. In highly productive waters, decomposing organisms deplete the profundal waters of oxygen that little aerobic life can exist there. The profundal zone is often part of the aphotic zone. The decomposition of organic materials can continue in the benthic and profundal zones if the matter falls through the water column before being completely digested by the pelagic bacteria. The cold dense zone is found below the thermocline, where the temperature falls rapidly, hence also called the hypolimnion zone. The Profundal Zone is the top layer of water in a body of water.

This zone is also dominated by planktons, both phytoplankton and zooplankton, microscopic crustaceans, and rotifers that serve as the primary level consumers. The profundal zone of a deep lake is a relatively larger portion of the lake volume, so the highly productive water of the epilimnion is small in comparison to the volume of profundal water and decomposition does not deplete the oxygen. These microorganisms serve as decomposers and convert organic matter into inorganic nutrients, thus, in turn, results in continuous recycling of inorganic nutrients. Oligotrophic or younger lakes have steep and narrow littoral zones whereas, eutrophic or older ponds have wide littoral zones.
