We rely on rivers for drinking water, irrigation, and more. Providing a home for fish, plants, animals, and people, rivers are essential for the survival of many species—including our own.
Are ecosystems supported by rivers?
Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow-moving water of pools. These distinctions form the basis for the division of rivers into upland and lowland rivers. … River ecosystems are prime examples of lotic ecosystems.
How do rivers support wildlife?
Wild rivers support the entire web of life
Countless species of fish, birds and other animals live in and along rivers and depend on them for their food. … Rivers also connect ecosystems to one other and affect landscapes far beyond the apparent surface of the water.

How does water support the river ecosystem?
Water for the environment supports the health of the river so that it can in turn provide for human needs. As water moves onto the floodplain, it releases carbon that energises the food web. River pulses trigger fish breeding and movement.
How do animals adapt to a river changing course?
Map turtles and softshell turtles are uniquely adapted to larger swift-moving rivers. Softshells have snorkel-like nostrils that allow them to breathe in shallow water while their flat, pancake-shaped shell is nestled in the sand. Birds and mammals have also adapted to exploit the aquatic habitats.
What type of ecosystem is a river?
