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.
What are the types of river ecosystem?
Rivers link terrestrial, freshwater and coastal marine systems in an open transport and migration route. The most obvious characteristic of river ecosystems is that of unidirectional flow driven by gravity.
What is the importance of river ecosystem?
River ecosystems are clearly important and at risk. Their direct economic importance to societies includes their use in transportation, water supply, energy, and provision of harvestable products.
What are the characteristics of river ecosystem?
The river ecology comprises of four dimensions namely the Length, Width, Depth and Time of the river flow. The physical characteristics of the river changes as it flows from mountain to ocean.
What are the types of ecosystem?
The different types of the ecosystem include:
- Terrestrial ecosystem.
- Forest ecosystem.
- Grassland ecosystem.
- Desert ecosystem.
- Tundra ecosystem.

- Marine ecosystem.
What are the three consumers found in the river ecosystem?
The micro consumers of rivers are the herbivores, predators and parasites. The decomposers or micro consumers are the worms, bacteria and fungi. In a stream ecosystem, food is constantly being produced, consumed and recycled.
What is River ecosystem services?
River Ecosystem Service Index (RESI) The performance of restoration measures in rivers and floodplains supporting water resource management and nature conservation may be significantly improved if the ecosystem services involved that are used by various sectors of society are known.
What is an ecosystem service provided by rivers?
River systems provide diverse ecosystem services (ES), such as flood regulation (regulating), fresh water (provisioning), nutrient cycling (supporting), and recreation (cultural), among others.
What is the importance of ecosystem?
Healthy terrestrial ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits. Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air.
What biotic factors are likely to be present in a river ecosystem?
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae.
Which type of ecosystem is river natural or artificial?
Some examples of natural ecosystems that fall within this category are lakes, rivers, ponds, streams, wetlands etc. Rivers and streams originating from mountains carry essential nutrients which are then deposited in lakes and ponds. Freshwater is also the habitat for a variety of plants, animals, and microbes. 2.
What are the biotic factors of a river?
For example in the river a biotic factor can be small frogs, plants, fish anything living in the river. In the sea the biotic factors are any large fish or sea creatures living in that area, also any small organisms like shrimp and other things you can see.
Which animals live in a river?

Turtles, ducks, otters, crocodiles, catfish, dragonfly and crabs can be found in rivers all around the world, and the Amazon river is even home to the rare and pink, freshwater dolphin.
What is an example of a standing water ecosystem?
Lakes and ponds are the most common types of standing-water ecosystems. Can also include bogs, prairie potholes, swamps, and freshwater marshes. The top-level of a standing-water ecosystem supports the plankton community. Plankton is a general term for organisms that drift in the water.
What are the 5 habitats of a river?
River beds, or the water channel itself. River banks, called the “riparian zone.” These include the land, trees, and water-loving animals and plants along the channel. Floodplains, or the low, flat land spreading out from the channel.
