There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time).
Standing freshwater biomes include ponds and lakes. Lakes are generally bigger and deeper than ponds. Some of the water in lakes is in the aphotic zone, where there is too little sunlight for photosynthesis.
Freshwater ecosystems encompass lakes, rivers, streams, wetlands, and groundwater. They provide essential services supporting human water security and biodiversity conservation. Freshwater ecology examines the physical, chemical, and biological components of these systems and their interactions.
Some of the best-known habitats of the freshwater biome are rivers and streams. Rivers and streams are flowing, or lotic, freshwater ecosystems, whereas lakes and ponds are still water, or lentic ecosystems.
A freshwater biome is a large community of flora and fauna (plants and animals) that live in water bodies with low salt content, usually less than 1%. Examples of freshwater biomes include lakes, ponds, streams, rivers and even some wetlands. Freshwater biomes differ from marine biomes.
Wetlands are areas of standing water that support aquatic plants. Marshes, swamps, and bogs are all considered wetlands. Plant species adapted to the very moist and humid conditions are called hydrophytes.
All land surfaces in the biosphere develop temporary bodies of fresh water following a rain. Although the total volume of fresh water in such localities is only a small fraction of that in permanent freshwater lakes, the biological role of temporary bodies of standing fresh water is considerable.
The aquatic (freshwater, or partly freshwater) biome include lakes, ponds, and wetlands (standing water) as well as rivers and streams (flowing water). Freshwater biomes are found in terrestrial landscapes and are therefore connected with abiotic and biotic factors influencing these terrestrial biomes.

Freshwater biomes include lakes and ponds (standing water) as well as rivers and streams (flowing water). They also include wetlands. Humans rely on freshwater biomes to provide aquatic resources for drinking water, crop irrigation, sanitation, and industry.
