Question 14

15. Which action will most likely cause a negative impact on the biodiversity of a small region? (4.4)

Accepted Answer

draining a wetland for the development of a new park

Answer

planting native species in a bare field to attract wildlife

Question 16

17. In a coastal marine ecosystem, various processes contribute to the carbon cycle. Which of the following best describes the natural carbon cycling in a coastal marine ecosystem? (4.2) County

Accepted Answer

Respiration by marine organisms adds carbon to the atmosphere, and photosynthesis by phytoplankton removes carbon from the atmosphere.

Answer

Combustion of fossil fuels adds carbon to the atmosphere, and the formation of coral reefs removes carbon from the hydrosphere.

Answer

Decomposition of plastic waste in the ocean adds carbon to the hydrosphere, and absorption of carbon dioxide by ocean water removes carbon from the geosphere.

Question 17

18. Shell-forming organisms such as corals and mollusks trap CO2 by forming their shells.  A marine ecosystem study has observed a decline in corals and mollusks due to ocean acidification.

Question 18

19. Recent studies of ice core samples have shown that during periods when the Earth's atmosphere contained higher concentrations of greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), the global temperatures were also elevated. This pattern suggests a strong relationship between greenhouse gas concentrations and Earth's climate.
Which of the following conclusions can most accurately be drawn from the correlation between high concentrations of greenhouse gases and global temperatures? (4.3) County

Accepted Answer

Higher greenhouse gas concentrations are associated with elevated global temperatures, likely due to a stronger greenhouse effect.

Answer

Higher greenhouse gas concentrations cause a decrease in global temperatures due to increased reflection of solar radiation.

Answer

Higher greenhouse gas concentrations in the atmosphere have no significant impact on global temperatures, suggesting other factors are more important.

Answer

The correlation between high greenhouse gas concentrations and elevated global temperatures is coincidental and unrelated to each other.

Question 19
