2. Fossil fuels are formed in the geological past from the remalne of living organisms. Petroleum products, such as coal and natural gas are considered fossil fuels. Why are these types of fuels considered NONrenewable? 3. When animal and plants die, microorganisms, fungi and insects are responsible for decomposition. These organisms also respire. Show an arrow on the diagram to indicate respiration by decomposers. Scientists are concerned that melting glaciers are exposing long frozen animals. When the ice melts, the animals thaw and begin to decompose. How will this affect the amount of CO, in the atmosphere?. 4. Large areas of land are being developed. In the process thousands of trees are being removed and bumed. How would this affect the cycle? 5. What activities can increase the amount of atmospheric CO,? 6. How could we decrease the amount of atmospheric CO,?

What type of energy capture would you expect from a bacterium living within the hydrothermal vents? O A. heterotrophic B. chemotrophic O C. phototrophic D. decomposer Moving to another question will save this response. End DII F5 PrtScn F8 Home F9 F6 F7 F2 F3 F4 & 近

Which one of the following statements is false? Group of answer choices Water plays the main role in  the increase in the mean global temperature referred to as global warming. Water does not cause global warming because the atmospheric lifetime of water vapor is short. The amount of energy absorbed when water evaporates is large due to its strong intermolecular forces. Water absorbs the greatest percentage of infrared radiation being emitted by the earth. The energy when released water condenses heats the atmosphere and fuels storms.

Classify the following statements as True or False. NO undergoes photodissociation to initiate the process of smog formation.:  The very cold tropopause layer is the major absorber of harmful UV radiation.:  In the stratosphere the temperature increases with increasing altitude.:  Temperature inversions are very useful, because the cause air pollution to disperse.:  Incoming solar radiation is primarily in the form of infrared radiation.:  Free radicals lose their energy spontaneously, reverting to a stable species by themselves.:  CO is removed from the atmosphere by reaction with the hydroxyl radical.: E A significant fraction of solar heat is converted to latent heat by evaporation of water.:  The Antarctic ozone hole reaches its peak during the antarctic winter.:  Free radicals last longer in the stratosphere than in the troposphere.:
