Water can be introduced into rivers and streams through surface ar runoff, springs, underground water discharge, melting ice and snow, and precipitation.
The greatest biodiversity occurs in the center sections of rivers, since the factors affecting life in rivers room optimal there. At the mouth the rivers, the water is murkier, which renders it more an overwhelming for plant life come thrive. The oxygen contents of rivers is also low in ~ the mouth to sustain good biodiversity. The water in ~ the source of the river has high oxygen content, but the width and depth are commonly less than they space in the center sections. The center sections have enough oxygen levels, moderate temperatures, and also adequate access to sunlight.
Which of the adhering to is no a characteristics of the resource of rivers and streams?a.high oxygen levelsb.freshwater fishc.cooler temperaturesd.murky waters
Rivers and also streams space flowing bodies of water. In the clinical community, a present is any kind of flowing body of water. In some countries, streams are characterized by their size. Because that example, in the unified States, a stream is a flowing body of water that is less than 60 feet wide. Various other than size, rivers and also streams have few differences. They space both an essential part of the water cycle, have actually a current, and also flow into an additional body that water.

The existing determines where organisms are located. In rivers or streams through a quick current, organisms that have actually the way to anchor themselves will be more likely to thrive. Swimming against a current requires a an excellent deal that energy, so organisms will tend to live toward the bottom that rivers and also streams. Oxygen contents is critical factor in where organisms will certainly be located as well. Oxygen level are greater at the source of rivers and also streams, therefore organisms that require greater levels the oxygen will certainly be discovered there. Organisms the require reduced levels of oxygen will certainly be uncovered nearer the mouth.
