Chapter 44, Problem 2CT
Summary Introduction
To explain:
The decrease in the amount of vegetation contributes to the rise in the atmospheric content of carbon dioxide.
Introduction:
Vegetation is a term that includes all plants from evergreen forests to grass land. Plants convert atmospheric carbon dioxide into oxygen through the process called photosynthesis. During photosynthesis plants use sunlight, water and carbon dioxide to produce sugar and oxygen.
Carbon dioxide is one of the “greenhouse gases” that causes global warming.

Students have asked these similar questions
Forests take in carbon dioxide from the air, thus it is called “carbon dioxide sinks” or “carbon sinks”.- What is the use of carbon dioxide in the forests? Explain.
Why does an urban park full of trees have a greater cooling effect than an equal-sized urban golf course covered in grass? Pick the BEST answer
a) Because trees sequester carbon into their wood
b) Because trees photosynthesize
c) Because trees create temperature differentials that improve airflow
d) Because trees transpire producing evaporative cooling and grass does not
In many areas, forests are burnt to clear land for agriculture. Explain how this method of deforestation would alter the carbon cycle.

- Carbon dioxide in the atmosphere traps heat. Scientists are concerned that too much carbon dioxide is being released into the air by human activity.

Carbon dioxide is produced by the burning of fossil fuels.arrow_forwardThe concentration of atmospheric carbon dioxide has increased since the beginning of the industrial age. Based on what you have learned in this unit, predict the effect of increased carbon dioxide on the rate of photosynthesis in the biospherearrow_forwardThe burning of fossil fuels releases CO2 into the atmosphereand is detrimental to the Earth’s ecosystems. Explain whythe use of biofuels, which also release CO2, is an improvement over fossil fuels.arrow_forward
- Scientific evidence indicates that the CO2 added to the air by the burning of wood and fossil fuels is contributing to global warming, a rise in global temperature. Tropical rain forests are estimated to be responsible for approximately 20% of global photosynthesis, yet the consumption of large amounts of CO2 by living trees is thought to make little or no net contribution to reduction of global warming. Explain why this might be the case.arrow_forwardIn China, air pollution from burning coal contributes to more than premature deaths per year.arrow_forwardScientific evidence indicates that the CO2 added to the air by the burning of wood and fossil fuels is contributing to global warming, a rise in global temperature.
