Lentic and lotic are the examples of which ecosystem

Lotic Systems In lotic systems, substratum-mobilizing spates result in burial of attached algae as small gravel, sand, and/or silt is redeposited when floodwaters recede (Power and Stewart, 1987; From: Algal Ecology, 1996 Related terms: • Macroinvertebrate • Diatom • Coarse Woody Debris • Springs (Water) • National Parks • Hot Springs • Lentic Systems • Biological Sciences R.W. Sanders, in Encyclopedia of Inland Waters, 2009 In the Benthos The benthos in both lotic and lentic systems tends to accumulate organic matter and detritus, which offers both a food source and a habitat for benthic protists. Attached and motile protists can occur in high numbers on and in the sediments. Attached heterotrophic organisms typically create a current to bring suspended food from the water (e.g., peritrich ciliates), or allow material to fall or swim into specialized feeding appendages (suctoria and heliozoans). Phototrophic species can form mats or biofilms that often have high abundances of cyanobacteria with or without protistan phototrophs. Motile protozoa move on and through these biofilms, and also at the surface and within the sediment. In sediments with relatively high organic matter content, gradients of oxygen, redox potential, pH, and other chemicals set up with sediment depth. As noted for the plankton, species that prefer oxic, microaerophyllic, or anoxic environments will move to appropriate depths in the sediment or will even leave the sediment and move into the water colum...

Inland aquatic systems are generally categorized as being either lentic or lotic habitats. Most of these are freshwater environments, although, depending on local climatic and geologic conditions, a wide range of salinities may exist, including brackish conditions characteristic of the Caspian and Aral Seas and the hypersalinities of the Great Salt Lake in Utah and the Dead Sea. These ecotopes may be perennial or ephemeral, the latter being associated mainly with strongly seasonal climates such as in the savanna belts (roughly 8 to 18° N and S), or with exceptionally porous subsoils, or with karst terrains. The term lentic (from the Latin lentus, meaning slow or motionless), refers to standing waters such as lakes and ponds (lacustrine), or swamps and marshes (paludal), while lotic (from the Latin lotus, meaning washing), refers to running water (fluvial or fluviatile) habitats such as rivers and streams. In coastal areas, lotic systems often grade into brackish estuaries before... • Ackermann, W. C., White, G. F., and Worthington, E. G., 1973. Manmade Lakes: Their Problems and Environmental Effects.

Table Of Contents • • • • There are two main types of aquatic systems, depending on whether their waters are moving or calm. The lotic ecosystems, also known as riparian ecosystems, are those whose waters are always flowing, except when there is a severe drought in which this movement is reduced, and may disappear altogether. In this article by Ecologist Verde we introduce you to the knowledge of the lotic ecosystems: what are they, their characteristics, examples and the difference between these and the lentic. Types of aquatic ecosystems Before we get into talking about lotic ecosystems, let's start by clarifying the main types of aquatic ecosystems: Freshwater ecosystems Freshwater ecosystems cover about 0.8% of the Earth's surface and provide habitat for organisms as diverse as reptiles, amphibians, and more than 40% of fish species. These ecosystems contain little or no salt, and can be differentiated into: rivers and streams (lotic ecosystems, fast moving), lakes, ponds and wetlands (lentic ecosystems, slow moving). Expand this information with these other Green Ecologist articles in which we explain why river water is fresh and we talk about freshwater aquatic ecosystems with examples. Saltwater ecosystems Marine or saltwater ecosystems are the largest existing ecosystems and cover more than 70% of the earth's surface, containing about 97% of existing water. They are home to disparate organisms, from corals and echinoderms to brown algae and dinoflagellates. These e...

A lotic system includes all flowing inland bodies such as creeks, rivers, streams, and so on. The ecology of flowing water is unique in many ways and is often shaped by the nature and behavior of the flowing water. A river, for example, is a flowing water body, usually unidirectional, with a source and an end. It is usually in constant physical change. At the source of the river, it is narrower in size, cold, fast-flowing, and rich in oxygen. Down to the end, it is usually wide in size, less oxygen, slow-moving, and warmer. That means lifeforms in a lotic system is not the same, as it depends on the following: 1. The nature and behavior of flowing water • The chemical makeup such as oxygen, pH, and alkalinity • The temperature of the water, depth of the water and how much sunlight can penetrate it, and so on • The velocity of the water • The stage of the river in its course. Flowing water at its source tend to flow very fast, whiles water at its end tend to flow very slowly with a lot of nutrients and particle deposition • The topography of the land (slopes, highlands, and lowlands) 2. The adaptation of its living organisms With the above picture of flowing water in mind, how are living organisms (plants and animals) adapted to survive in these flowing water bodies? • Organisms in these waters have suckers and hooks that help them stick to the water-bed, rocks, or plants. • Some of them also have a streamlined body that helps them swim against water currents. • Plants such...

Further information: Aquatic ecosystems perform many important environmental functions. For example, they In addition to environmental functions, aquatic ecosystems are also used for human recreation, and are very important to the Biotic characteristics (living components) [ ] The biotic characteristics are mainly determined by the organisms that occur. For example, wetland plants may produce dense canopies that cover large areas of sediment—or snails or geese may graze the vegetation leaving large mud flats. Aquatic environments have relatively low oxygen levels, forcing adaptation by the organisms found there. For example, many wetland plants must produce Autotrophic organisms [ ] Chemosynthetic bacteria are found in benthic marine ecosystems. These organisms are able to feed on Riftia pachyptila) 1.5m in length and clams ( Heterotrophic organisms [ ] Abiotic characteristics (non-living components) [ ] An ecosystem is composed of The amount of dissolved oxygen in a water body is frequently the key substance in determining the extent and kinds of organic life in the water body. Fish need dissolved oxygen to survive, although their tolerance to low oxygen varies among species; in extreme cases of low oxygen, some fish even resort to air gulping. Nutrient levels are important in controlling the abundance of many species of algae. The salinity of the water body is also a determining factor in the kinds of species found in the water body. Organisms in marine ecosystems tolera...

It includes all non-flowing (still waters) such as ponds, swamps, bogs, lagoons, lakes, and so on. It also includes wetlands (areas of land that get covered with water periodically). Lentic systems usually do not have a source, as they form in places where the groundwater reaches the earth’s surface. Sometimes, water will stay on the earth’s surface due to the saturation of the underlying land. Some lakes and ponds are created by humans for commercial and recreational use. Animals and plants in a lentic system behave and adapt differently because there are various zones of every lentic system with different abiotic conditions. The diagram below illustrates the zones of a lentic system. Zones of a lentic system Littoral Zone: This zone forms the banks or boundary of the water. There is usually warmer and shallow water, with lots of plants such as reeds and cattails. Many of the plants are rooted in the muddy floor and their leaves form a good hideout for insects and fish. There is a lot of fish, frogs, reptiles, and insects in this zone. Limnetic Zone: It is the zone after the Littoral zone, extending a few meters into the water body. Fish swim freely here, with some plants floating on the water. There is enough sunlight here, and algae and plankton usually thrive here. Profundal Zone: This zone extends beyond the Limnetic zone and is a deeper region of the water. Here, there is usually very little or no sunlight. It is cooler. Living things in this region depend on driftin...

Lakes and ponds (also known as lentic systems) are a diverse set of inland freshwater habitats that exist across the globe and provide essential resources and habitats for both terrestrial and aquatic organisms. Although widely distributed and vital for many species, including humans, these habitats account for just over 3% of the Earth's surface (Downing et al. 2006). Importantly, these rare systems are increasingly threatened by the human demand for freshwater as well as human activity (Dudgeon et al. 2006). Recent evidence suggests that freshwater systems are more imperiled than marine and terrestrial ones (Sala et al. 2000, Dudgeon et al. 2006). Effective conservation and management of these systems relies on our ability to fulfill the growing human demand for freshwater while maintaining system integrity.The study of lentic systems is conducted within the field of limnology. Limnology is the study of the structural and functional interrelationships of organisms of inland waters as they are affected by their dynamic physical, chemical, and biotic environments (Wetzel 2001). Several excellent books published within the past decade provide in-depth coverage of lakes and ponds (Wetzel 2001, Brönmark & Hansson 2005, Moss 2010). Another excellent resource is the Encyclopedia of Inland Waters (2009). In this article, we present a brief overview of lentic systems and refer the reader to specific literature for more detailed information. Physical and Chemical Structure Lentic ...
