This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
Freshwater marsh, Naselle River, Washington Freshwater marsh in Kittery Point, Maine. A freshwater marsh is a non-forested marsh wetland that contains shallow fresh water, and is continuously or frequently flooded. [1] [2] Freshwater marshes primarily consist of sedges, grasses, and emergent plants.
White water lilies are a typical marsh plant in European areas of deeper water. Many kinds of birds nest in marshes; this one is a yellow-headed blackbird.. Marshes provide a habitat for many species of plants, animals, and insects that have adapted to living in flooded conditions or other environments. [1]

The organisms that live around or in a river such as fish, aquatic plants, and insects have different roles, including processing organic matter and predation. Rivers have produced abundant resources for humans, including food, transportation, drinking water, and recreation.
The assortment of riparian zone trees varies from those of wetlands and typically consists of plants that are either emergent aquatic plants, or herbs, trees and shrubs that thrive in proximity to water. [46] In South Africa's fynbos biome, Riparian ecosystem are heavily invaded by alien woody plants. [47]
[1] [2] Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. [2] Mangroves are salt-tolerant and are adapted to live in harsh coastal conditions. They contain a ...
The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...
