Pond Pictures: A Depiction of the Wetland Ecosystem
A collection of pond pictures drives us to the conclusion of a small world underneath the depths of the water. A vast water ecosystem is present within a depth of 12-15 feet inside the water. There are various aquatic as well as terrestrial organisms dependent on this shallow water ecosystem. Again, many organisms depend on ponds for food, shelter and other basic needs for survival.
POND PICTURES: A SHALLOW ECOSYSTEM:
An area filled with water either naturally or artificially and is smaller than a lake is called a pond. It may naturally arise in floodplains as a part of the river system or be an isolated depression. Again, it may be fresh, saltwater or brackish. It usually contains shallow water along with marsh and aquatic organisms interacting together. A large number of animals like fish, tadpoles, frogs, ducks, etc. along with various types of plants are present in the pond ecosystems.
FORMATION OF PONDS:
Ponds can be formed from a wide range of natural processes. Any type of depression in the ground which may collect or retain precipitation can be termed as a pond. These depressions are formed by various geological and ecological events. For instance- rivers may leave behind pond after their spring flooding. Moreover, in areas with organic soil fire can also leave behind depressions during the time of drought. These may become ponds when the normal water level returns.
CHARACTERISTICS OF PONDS:
A notable feature of the pond is the presence of standing water. This is a dwelling place for abiotic and biotic components. Usually, wetland fringes the whole margin of the pond that supports the aquatic food web, provide shelter for its inhabitants and stabilize the shore of the pond. A pond is the combination of three different food webs, based on- large plants, decayed plants and algae. Ponds usually have a large number of different animals that feed on various food sources.
FACTORS IMPACTING POND LIVES:
There are various factors that impact the type of life in ponds. Again, these include depth and duration of water level, shade, presence or absence of inlets and outlets, effects of grazing animals and salinity.
FUNCTIONS OF POND ECOSYSTEM:
The pond ecosystem consists of both abiotic and biotic factors. The abiotic factors include light, temperature, dissolved oxygen, carbon dioxide, etc. while biotic factors include producers (green plants, algae, etc.), consumers (fishes, ducks, etc.) and decomposers. The functions of the pond ecosystem are based on the interaction between these factors. The functions are given below:
- Pond ecosystem provides a home for wildlife
- It plays an important role in cycling water and nutrients.
USES OF PONDS:
Ponds can be used in various sectors of human civilization. These water bodies provide water for agriculture and livestock, helps in habitat restoration, serves as a breeding ground for fishes etc. They can also be used as irrigation reservoirs in the time of drought.
CONSERVATION AND MANAGEMENT:
As ponds are small in size, human activities easily disrupt the pond ecosystem. For instance- drainage of ponds may cause frequent problems in the sector of agriculture. Again, due to the overgrazing of cattle, the pond may become a muddy hole. Excessive fertilizer being washed into the ponds may cause explosive growth of aquatic plants and loss of rooted plants and other aquatic species.
The construction of roads and other structures near may cause the degradation of life in ponds. If ponds are constructed artificially, we will be able to make wildlife viewing opportunities as well as treat wastewater. Roads and other constructions near ponds must be avoided at all cost. Another important way to create natural ponds is to restore the river so that they can flood the depressions.
Ponds may be a small ecosystem but it is home to many organisms. It deserves as much attention and conservation as any other ecosystem. As a result, when we will look through the collection of pond pictures in the next decades, we can again conclude it as the same small world underneath the shallow water.
