Answer:

Since the mouth of a river typically has lower levels of oxygen and the area near the source has higher levels of oxygen, catfish and carp can thrive at the mouth and trout, which require higher levels of oxygen, thrive at the source.

☆ANSWER ☆

Since the mouth of a river typically has lower levels of oxygen and the area near the source has higher levels of oxygen, catfish and carp can thrive at the mouth and trout, which require higher levels of oxygen, thrive at the source.

Catfish and carp require less oxygen than trout. The mouth of a river generally has less oxygen and the area closest to the source has more oxygen, so that from the catfish and trout require more oxygen than normally found in the source.
