It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.
<h3>What is river and stream?</h3>
A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.
On the other hand, a stream is a small river or a body of moving water confined by banks.
Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.
Therefore, it is true that rivers and streams are biodiverse ecosystems that are sensitive to change.
