- 6. Multiple ChoiceThe presence of wastes, such as plastic bags and motor oil, in lakes and streams miles away from developed areas suggests that:ecosystems are interconnected and human action can alter ecosystem equilibrium.recycling programs have failed to conserve biotic resources.natural processes can alter ecosystem stability.direct harvesting practices have led to irreversible destruction of ecosystems.
- 7. Multiple ChoiceWhen 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.

Educate society on the harmful effects and gradually replace fossil fuels with alternative renewable resources
Fund scientific research for discovering new energy sources and use the remaining supply of fossil fuels until then.
Create an environmental policy that would ban the use of all fossil fuels due to the negative environmental effects.

Climate change is predicted to have an impact on Earth's biodiversity. What could be a consequence of climate change on marine biodiversity?
An increase in the temperature of the ocean may cause bleaching of corals, thus dramatically reducing biodiversity
An increase in the temperature of the ocean will cause coastal wetlands to shrink, thus decreasing biodiversity

Monoculture is the agricultural practice of producing a single crop over a large area. In the 1980s, scientists discovered and produced a monoculture of cotton that was eventually planted throughout the southern states.
What could be one possible side effect of the monoculture cotton?
The farmers could destroy the land due to lack of crop rotation.
Supply could not meet demand because of the single cotton crop.
The price of cotton could escalate because of lack of competition.
Disease could spread throughout the crop due to lack of genetic variation.

DDT and other pesticides used over 50 years ago are still affecting the environment today. Scientists have found these substances in recent glacier runoff. Glacier runoff occurs during the summer, when precipitation that has fallen on glaciers during the winter is released. Ice layers from existing glaciers have been analyzed. The results of this analysis show that the concentrations of DDT and other pesticides were highest about 10 years after the use of these substances was banned.
This information shows that…
precipitation helps to break down pesticides.
it takes humans over 50 years to analyze a glacier.
the decision of one human generation may have an impact on future generations.
