Rivers are home to fish and wildlife: Freshwater fish like bass, perch, bluegill, and catfish. Many invertebrates that provide food for fish. Protected, endangered and threatened species.

Why are rivers important to animals?
Rivers provide excellent habitat and food for many of the earth’s organisms. Other animals such as bears catch fish from rivers. River deltas have many different species of wildlife. Insects, mammals and birds use the delta for their homes and for food.
How can rivers help us?
Humans use rivers for irrigation in agriculture, for drinking water, for transportation, to produce electricity through hydroelectric dams, and for leisure activities like swimming and boating. Each of these uses can affect the health of a river and its surrounding ecosystems.
Why are rivers important to the ecosystem?
Today river ecosystems provide essential benefits and services to society, including water purification, transport and transformation of organic matter and other materials, nutrient cycling, flood control, and others (Costanza et al., 1997).
Which animals lives in the river?
More Than Fish Snails, worms, turtles, frogs, marsh birds, mollusks, alligators, beavers, otters, snakes, and many types of insects live there too. Some unusual animals, like the river dolphin and the diving bell spider, are freshwater creatures.
How do humans depend on rivers?
They act as a sponge and regulate the water volume, as they cut off flood peaks and release water during low-flow conditions. Nearly everywhere on Earth, people depend on rivers for fresh water supply and sanitation purposes.
Why are rivers important to man?
First, the supply of water was vital. Humans need a constant supply of water to survive and rivers provide freshwater that can be drunk safely. Second, the river itself could be a source of food if it contained fish. Third, the water from rivers could help with early agriculture.
What is river and its importance?
Rivers are the significant sources of water and carry water and nutrients to areas worldwide. Their role is very vital in the water cycle and also as drainage channels for surface water. Rivers drain about 75% of the land surface of the Earth.
What do rivers provide us with?
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.
Why is river polluted?
Sources of pollution If large amounts of fertilizers or farm waste drain into a river the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae, called eutrophication, leads to pollution.
How do rivers affect ecosystems?
Rivers exchange water, materials, energy, and nutrients, in a reciprocal manner with the surrounding environment. River water quality, sediment characteristics, and biological communities, all reflect characteristics of the upstream, and even the downstream environment.
How does a river support a balanced ecosystem?
Living in flowing water can be beneficial to plants and algae because the current is usually well aerated and it provides a continuous supply of nutrients. These organisms are limited by flow, light, water chemistry, substrate, and grazing pressure.
Is River a natural ecosystem?
River ecosystems are amongst the ecosystems with the largest rates of biodiversity loss (Dudgeon et al., 2006), and, especially in water-scarce areas, human societies allocate only a small volume of water (Arthington et al., 2006).
What lives in a stream?
The aquatic organisms in streams include fish, of course, but go far beyond that. Molluscs, like clams and mussels. Amphibians, like salamanders and frogs. The larvae of many insects, like dragonflies, damselflies, and mayflies.
What animals and plants live in a lake?
Animals in the lakes include plankton, crayfish, snails, worms, frogs, turtles, insects, and fishes. Plants include water lilies, duckweed, cattail, bulrush, stonewort, and bladderwort.
What animal can be a pet?
Other animals commonly kept include: rabbits; ferrets; pigs; rodents, such as gerbils, hamsters, chinchillas, rats, mice, and guinea pigs; avian pets, such as parrots, passerines and fowls; reptile pets, such as turtles, alligators, crocodiles, lizards, and snakes; aquatic pets, such as fish, freshwater and saltwater
