Lake Ecosystem

Lake Ecosystem is the ecosystem of a lake, swamp or pond and included in the environment are biotic interactions and abiotic interactions. Lentic refers to still or standing water and is derived from Latin word Lentus that means sluggish. Lake ecosystems can be compared with lotic ecosystems that involve flowing terrestrial waters like streams or rivers. These systems are diverse and range from temporary, small rainwater pool couple of inches deep to Lake Baikal that has maximum deepness of 1740 meters. The common difference between ponds or pools and lakes is vague, however Brown states, which pools and ponds have their complete bottom surfaces exposed too light, while lakes don’t.

Additionally, quite a few lakes become seasonally the shore and bottom regions, as ponds feature deep bottom areas not exposed to light. Lake Ecosystem have an extra zone called profundal. You will find bacteria in all areas of lake waters and free living forms are linked with decomposing organic material called biofilm on plants or rocks surfaces. Other forms are linked with lentic animals’ guts as well as bedbugs or in commensal relationships. Algae, including periphyton and phytoplankton are main photosynthesizers in lakes and ponds. Phytoplankton are seen roving in water column of pelagic area.

Macrophytes or Plants found in Lake Ecosystem live in pelagic and benthic areas and can be combined as per their growth of manner. Emergent macrophytes rooted in substrate with flowers and leaves extending into air; floating leaved macrophytes rooted in substrate with floating leaves; submersed macrophytes not rooted in substrate and floating underneath surface; free floating macrophytes not rooted in substrate and floating on surface. These different macrophytes forms mainly occur in several benthic zones with developing vegetation adjacent to shoreline.

Fish mobility, sensory capabilities and size enable them to make use of wide prey base, layering numerous zonation areas. Like invertebrates, feeding habits of fish can be characterized into guilds. In pelagic area, herbivores graze on macrophytes and periphyton. Carnivores include fishes, which feed on zooplankton in water column insects at the surface of water on benthic structures, or in sediment and those, which feed on other fish.

Fish, which consume gain energy and detritus by giving out its organic material, are known as detritivores. Omnivores consume broad array of prey surrounding faunal, detrital and floral material. At last, members of parasitic guild attain nutrition from host species, typically large vertebrate or another fish. Fish taxa are flexible in their feeding roles, altering their diets with prey availability and environmental conditions. Most of the species undergo diet shift as they develop and is expected that all single fished occupy numerous feeding guilds within their lifetime.

The biodiversity of Lake Ecosystem augments with surface area of pond or lake and is attributable to superior likelihood of partly terrestrial species of finding a bigger system. Due to bigger systems usually have bigger populations; the chance of extermination is reduced. Extra factors such as pH, temperature regime, habitat complexity, nutrient availability, competition, predation and speciation rates have been simultaneous to plenty of species found in these systems.
