A factory located near a river pumps heated water into the river. The heated water decreases the amount of oxygen in the river. A STS class is discussing what this decrease in oxygen would do to the river. Bam thinks less oxygen would change the type of organisms that live in the river. Mel thinks the type of organisms would stay the same, but there would be a lot less organisms. a.    Who do you agree with? Bam?Mel? both Bam and Mel? b.    Why are they right? What would happen if oxygen in a stream decreases?
