When fertilizers run off farmland into streams and ponds, the nitrogen content of the water increases. This can lead to rapid growth of algae in a process called eutrophication. How can this process affect other organisms in the water?

• Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.
• The water becomes better able to support aerobic organisms.
• The algae provide food for fishes and other organisms, leading to decreased algae populations.
• The extra nitrogen provides additional food for the other organisms, increasing their population.

How do you prove that humans are having an negative impact on Earth? What data shows that?

• Showing an increase in tourism to a certain region, the previously had little.

• Showing an increase in number of species extinct after deforestation occurring.

• Showing an increase of animals moving to an area.

• Showing the positive things that have occurred due to human activity.

How does overuse of a resource impact the environment?

• If a resource is depleted (all used up), it can be made again easily, so it does not impact the environment at all.

• If a resource is depleted (all used up), it can cause animals to starve and go extinct.

• If a resource is depleted (all used up), something else can be used in its place, so it does not impact the environment at all.

• If a resources is depleted (all used up), it doesn't matter, so it does not impact the environment at all.

Continued depletion of the ozone layer will most likely result in

• an increase in skin cancer among humans 
• a decrease in atmospheric pollutants 
• an increase in marine ecosystem stability 
• a decrease in climatic changes

The acidity of a local stream would most likely be affected by

• a change in the percentage of decomposers living in the stream
• a new source of air pollution 
• a new predator species being introduced to the ecosystem
• a decrease in the amount of sunlight that reaches the stream
