ENV SCI Unit 3: District Assessment Prep Pt 2

During a dry season, a farmer can cause an environmental change by regularly watering crops. This environmental change can effect the stability of the field's ecosystem by causing the ecosystem to become

• less stable, as the crops in the field receive more water than they would with rain.

• less stable, as the crops in the field outnumber the native grasses in the field.

• more stable, as the crops in the field do not dehydrate and die off.

• more stable, as the crops in the field receive too much water.

Global measurements indicate that, in the late 2000s, sea levels steadily rose. Rising sea levels lead to the migration of marshlands further inland. The environmental changes caused by rising sea levels have the potential to

• alternately increase and decrease the biodiversity of marsh habitats.

• increase the stability of marsh habitats.

• increase the biodiversity of organisms in marsh habitats.

• decrease the stability of marsh habitats.

The release of pollutants into marine waters can cause harmful algae to bloom. The algae may cover large sections of coral reefs. How do the algae affect the coral?

• They harm the coral by preventing the coral from becoming parasites of the algae.

• They benefit the coral by providing the coral with many nutrients.

• They benefit the coral by increasing the water temperature.

• They harm the coral by preventing them from receiving enough sunlight.

As the populations of cities increase, and buildings take over the wild landscape, many people are making an effort to form preserves, which keep the plant and animal life of an area in its natural habitat. What is the most likely reason these people are so determined to make these preserved areas?

• Preserves are like giant parks, and parks make a city prettier.

• To prevent too many people from being able to move into the city.

• Preserves make a lot of money for a city and can pay for more buildings.

• Without their natural environment, plant and animal species will become extinct.

Which of the following statements is correct?

• An increased demand for energy leads to an increased depletion of resources and detrimental environmental risks.

• An increased demand for resources leads to increased energy production and environmental benefits.

• An increased demand for environmental protection leads to increased resource depletion and decreased energy use.
