<p>Hi guys… I am doing homework for my ecology class and there is one question</p>
<p>which I really don’t understand… The question was </p>
<p>“Explain the impact of Topography (of a stream) on type of biological organisms in a body of water”</p>
<p>My hypothesis is that the hilly a stream is, the more oxygen the stream </p>
<p>gains,</p>
<p>Anyway, can you guys give me a helping hand please?</p>
