The water cycle plays a significant role in terrestrial ecosystems because it is the major component, by weight, of all organisms water evaporates from oceans. Wetlands – including swamps, bogs, marshes, and lagoons – cover 6% of the worlds land surface and play a key role in local ecosystems and water resources many of them have been destroyed, but the remaining wetlands can still play an important role in preventing floods and promoting river flows. Ramsar convention on wetlands - information on wetland ecosystem services water security and ecosystem services: the critical connection - find out more about the importance of water in supporting human survival and economic livelihoods, as well as water needs of ecosystems.
Clean, fresh water is an essential ingredient for a healthy human life, but 11 billion people lack access to water and 24 billion don’t have adequate sanitation by 2025, two-thirds of the world’s population may be facing water shortages. Freshwater ecosystems–lakes, rivers, and the smaller ponds and streams–make up only two percent of earth's water resources, and only one percent remains drinkable. Directories of resources water, health and ecosystem linkages most of the earth's surface is covered by water, and most of the human body is composed of water – two facts illustrating the critical linkages between water, health and ecosystems.
Under water ecosystems play a big part in our everyday livesthink about life without fish, reefs, and underwater plants underwater vegatation plays a huge part in our lives, and all we do is take it. An aquatic ecosystem is an ecosystem in a body of water communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems the two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Salt water is water that contains roughly 35% salt it is found in the world's oceans and seas, as well as in smaller amounts in brackish water salt content in water can differ within the same body of water it is less salty where fresh water runoff mixes into the ocean or sea, typically from a.

Freshwater ecosystems can be classified as lotic, where the water flows, and lentic, where the water is nearly stationary examples of lotic ecosystems include creeks, rivers and springs examples of lentic ecosystems include swamps, bogs, ponds and lakes. Another major type of aquatic ecosystem is a freshwater ecosystem, which consists of lentic or slow-moving water ecosystems, lotic or fast-moving water ecosystems and wetland ecosystems lentic ecosystems include ponds and lakes, which break down into smaller zones or ecosystems including littoral zones, open-water zones and deep-water zones. Our freshwater ecosystems are impacted by changes in the water cycle, drainage, pollution and sedimentation, nutrient enrichment, deforestation and invasion by pests these impacts have had significant consequences for our freshwater biodiversity which is vulnerable to invasion, interbreeding, overharvest and habitat loss and degradation.
