Which substances necessary for human life is produced by ocean organisms that photosynthesize?
Oxygen!

Will dumping industrial waste into nearby streams be harmful to a watershed?
Yes. More chemicals will typically be harmful

When coal exists in a mountain area, mining companies sometimes use explosives, removing all of the soil and rock that lie above the coal. The soil is then dumped into nearby valleys and streams, this has caused a lot of problems, including loss of forests, danger from flying debris, and dust clouds from the blasts. Do you think this can affect the watershed nearby?
Yes, via contamination of the Water Supply

Being upstream from pollution is beneficial or harmful?
Beneficial, as the pollution won't be pulled down towards you
400
Are each of the following Positive or Negative
1. Chemicals can enter groundwater reserves by percolation
2. Aquatic organisms can be impacted by agricultural runoff

This Describes what?
The factories produce pollution, which ends up in the water, reducing the number of animals in the oceans. The fishing industry then cannot catch enough fish to meet the demand.
