What is the role of ground water in maintaining ecological balance?
Groundwater maintains wetlands and their ecosystems. Groundwater makes part of base flows of rivers and support river in ecosystem. … Fresh water sustains biomass growth in terrestrial ecosystems, and provides key ecological services—maintaining biodiversity, sequestering carbon and combating desertification.
What are the function of groundwater?
Groundwater has storing, filtering and transforming capacities, and regulates atmospheric, hydrological and nutrient cycles. Groundwater stores and partly transforms CO2, energy, plant nutrients and other chemical substances. Groundwater can act as sink in the carbon cycle.
How does groundwater affect the ecosystem?
Too much ground water discharge to streams can lead to erosion and alter the balance of aquatic plant and animal species.
Why is it important to maintain the ecological balance of the ecosystem?
Favorable ecosystem ensures that each organism thrive and multiply as expected. They get enough food to keep them alive. Ecological balance is also important because it leads to the continuous existence of the organisms. It ensures that no particular species is exploited or overused.
What is under ground water?
Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
What kinds of aquatic ecosystems exist in groundwater?
for communities around the world. Many aquatic eco- systems, including wetlands, lakes, rivers, springs, and subterranean ecosystems, as well as many species, also rely on groundwater to meet their water requirements. 1 These are known as groundwater-dependent ecosystems (GDEs).
Why is groundwater important to the water cycle?
Groundwater is an important part of this continuous cycle as water evaporates, forms clouds, and returns to earth as precipitation. Surface water evaporates from by energy of the sun. The water vapor then forms clouds in the sky. … Other precipitation seeps into the ground and is stored as groundwater.
Why is underground water important to human beings and environment?
Groundwater is a prime natural resource in the Earth. It not only supports all types of life forms to exist in the Earth but also helps in the growth of human civilization. It quenches thirst and fulfils all the house-hold demands. Groundwater is used for the irrigation purposes.
What is the source of ground water?
Groundwater sources are beneath the land surface and include springs and wells. As can be seen from the hydrologic cycle, when rain falls to the ground, some water flows along the land to streams or lakes, some water evaporates into the atmosphere, some is taken up by plants, and some seeps into the ground.
Does groundwater contribute directly to the water needs of plants?
Water stored underground in the saturated and subsurface zones below the soil are important sources of water for plants in water-limited ecosystems. The presence of deep-rooted plants worldwide, however, suggests that the use of groundwater is not restricted to arid and seasonally dry ecosystems.
Why is groundwater an important source of freshwater storage?
Groundwater is an important source of freshwater, partly because it accounts for approximately 30% of the Earth’s freshwater. Groundwater is an important source of freshwater for areas that do not have access to other sources of freshwater, such as areas that are experiencing droughts.
What will happen if the groundwater is depleted?
Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence. Such effects, while variable, happen to some degree with any ground-water use.
