Nitrogen pollution enters Earth's freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state. Which of the following would most likely increase the negative effects of nitrogen pollution?

• Loss of biodiversity in the wetlands

• ​​​​​​​The introduction of a new species of plant

• Using fertilizers that do not contain nitrogen

• ​​​​​​​Increase of biodiversity in the wetlands

Human activity can destroy coral reefs. Because so many organisms depend on the coral, this can have a negative effect on the ecosystem in the shallow ocean waters. Which of the following solutions will most likely offer the best way for humans to repair the damage and improve the health of the ecosystem?

• Design nets to catch the kinds of fish that use coral reefs as a food source

• Submerge large structures on which new coral reefs can form and grow

• Introduce non-native species into the shallow ocean that don't depend on coral

• Use submarines to gather data on the amount of coral reefs lost each year
