What can be found in a river?
Biological parameters of a river habitat include: fish, aquatic wildlife and vegetation, macroinvertebrates (insect larvae, mussels), and microorganisms such as bacteria or algae. via
What plants and animals live in rivers?
Streams are smaller and can converge to create rivers. Rivers and streams are fresh water and hold up to 3 percent of the Earth's fresh water. Freshwater plants include algae, bulrushes and cattails, and freshwater animals include crayfish, fish and eels. via
What kind of living things are found in rivers and lakes?
Rivers and lakes are usually freshwater habitats that support many forms of life, from algae and plankton to insects and fish to larger wildlife. The food chain and the interdependence of the wildlife in these habitats can be disrupted by pollution, pesticides, and erosion. via

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. via
Is there life in waterfalls?
Waterfalls also help to keep the eco system alive and this is seen through the abundant life that surrounds the waterfalls from people, plants to animals like lizards, reptiles, wild birds and many others. via
