1. The correct answer is option D. all of the above.
Global climate change will bring changes in temperature such as heat waves, droughts, volcanic eruption, deforestation, extinction of species due to large shift in temperatures, changes in precipitation such as heavy snowfall, ocean acidification, and ozone depletion.
2. The correct answer is option C, ozone.
Ozone is not released by trees into the atmosphere. Plants have chlorophyll and in the presence of sunlight plants uses sunlight and carbon dioxide to form glucose and oxygen.
6CO₂ + 6H₂O -> C₆H₁₂O₆ + 6O₂
During transpiration plants exhale water vapor through the stomata, tiny pores that are found on the surface of the leaves.
Thus trees never release ozone into the atmosphere.
