Structure of Lentic Habitat

	Structure of Lentic Habitat Lentic ecosystems include all standing water (freshwater) habitats such as lakes, ponds, marshes, swamps, bogs, etc. Lakes are inland depressions containing standing water. They may vary in size from small ponds of less than a hectare to large lakes covering thousands of square kilometres. They may range in depth from a few centimetres to over 1666 metres.
Ponds however are considered as small bodies of standing water so shallow that rooted plants can grow over most of the bottom. Most ponds and lakes have outlet streams and both are more or less temporary features on the landscape. The aquatic habitats of lake and pond remain vertically stratified in relation to light intensity, wavelength absorption, hydrostatic pressure, temperature etc. In a lake there are well recognised horizontal strata which include:
i. Shallow water near the shore forms the littoral zone. It contains upper warm and oxygen-rich circulating water layer which is called epilimnion. The littoral zone includes rooted vegetation. ii. Sublittoral zone extends from rooted vegetation to the non-circulating cold water with poor oxygen zone, i.e. hypolimnion. iii. Limnetic zone is the open water zone away from the shore. It is the zone upto the depth of effective light penetration where rate of photosynthesis is equal to the rate of respiration.
iv. Profundal zone is the deep water area beneath limnetic zone and beyond the depth of effective light penetration. v. Abyssal zone is found only in deep lakes, since it begins at about 2,000 meters from the surface. Ponds have little vertical stratification. In ponds, the littoral zone is larger than the limnetic zone and Profundal zone. In a small pond the limnetic and Profundal zone are not found.
