Over the past 200 years, people have been cutting down forests all over the world at a very fast rate. This has added large amounts of carbon dioxide to our atmosphere. Part of the reason is that when trees are burned, they release carbon dioxide. Why else would cutting down trees increase the amount of carbon dioxide in the atmosphere? A. Trees make carbon dioxide through photosynthesis. B. Trees, like all plants, use up carbon dioxide. C. Trees provide shelter for other living things that produce carbon dioxide. D. Trees give shade, which cools Earth's surface.
Question
Over the past 200 years, people have been cutting down forests all over the world at a very fast rate. This has added large amounts of carbon dioxide to our atmosphere. Part of the reason is that when trees are burned, they release carbon dioxide. Why else would cutting down trees increase the amount of carbon dioxide in the atmosphere? A. Trees make carbon dioxide through photosynthesis. B. Trees, like all plants, use up carbon dioxide. C. Trees provide shelter for other living things that produce carbon dioxide. D. Trees give shade, which cools Earth's surface.
Solution
The correct answer is B. Trees, like all plants, use up carbon dioxide.
Here's why:
-
Trees absorb carbon dioxide (CO2) from the atmosphere during photosynthesis, a process in which they convert CO2 and sunlight into oxygen and glucose.
-
When trees are cut down, they can no longer absorb CO2. This means there is more CO2 left in the atmosphere, contributing to the greenhouse effect and global warming.
-
Additionally, if the trees are burned or left to decompose after being cut down, they release the CO2 they had previously stored back into the atmosphere, further increasing the amount of atmospheric CO2.
So, while options A

Global Warming and Its Causes Global warming is a result of an increase in greenhouse gases. Greenhouse gases are released into the atmosphere deforestation and combustion of fossil fuels. Deforestation is a major contributor to global warming. Forests help to maintain the levels of oxygen in the air that make it possible for us to survive. , there has been a surge in the levels of carbon dioxide in the air the depletion of vast stretches of forests. , other factors, such as the release of CFCs from refrigerators and pollutants from industries into the atmosphere, are also responsible for global warming.
Read the following passage:Without trees returning water vapor back into the atmosphere, the water cycle becomes critically disrupted. When trees are cut down, there is no longer a canopy to shade the forest during the day and hold in heat at night. This results in extreme temperature swings. Finally, trees absorb greenhouse gasses that contribute to global warming. Fewer trees mean that more of these gasses are released into the atmosphere.Which statement best describes the main idea of this passage?A.Planting more trees can help reduce the energy costs of heating and cooling homes.B.The loss of trees has a major impact on the global climate.C.Global warming is caused by a lack of moisture in the atmosphere.D.People need to reduce their consumption of paper and lumber products.SUBMITarrow_backPREVIOUS
