Unit 1 Test: Environmental Studies First and last name Question 1/22 Name the process that involves moisture from vegatation rising into the atmosphere A. B. C. D. Evaporation Condensation Ammonification Transpiration Question 2/22 What do biogeochemical cycles represent? A. B. C. D. How certain nutrients move through the environment and are continually used and recycled How energy moves through trophic levels of an ecosystem How the adaptations of organisms change based on environmental pressures How biotic changes destroy unstable ecosystems Question 3/22 Name the compound to which humans and animals in the biosphere exhale A. B. C. D. Oxygen Carbon Dioxide Hydrogen Nitrogen Question 4/22 When leaves and other vegetation break down, they produce this compound: A. B. C. D. H2O Carbon DIoxide Ammonia Nitrogen Question 5/22 When water rises into the atmosphere, this is called: A. B. C. D. Heat rising cycles Transpiration Evaporation Elevation Question 6/22 Biogeochemical cycles demonstrate how nutrients are created and destroyed A. True - With every cycle comes new nutrients from the Earth that cycle back into the biosphere B. False - Matter is never created nor destroyed. Only recycled. 1 Unit 1 Test: Environmental Studies Question 7/22 Which of the following does NOT add carbon to the atmosphere? A. B. C. D. Cellular respiration Photosynthesis Decomposition Fossil fuel combustion Question 8/22 In which stage of the nitrogen cycle is atmospheric nitrogen converted into biologically usable forms? A. B. C. D. Nitrogen Fixation Denitrification Decomposition Ammonification Question 9/22 Sleet, snow, hail, and rain are examples of: A. B. C. D. Different forms of water Precipitation Fall weather Results of the water cycle Question 10/22 Which of the following is an example of how biogeochemical cycles are important to sustaining life? A. B. C. D. New carbon atoms are created during the carbon cycle. Oxygen atoms are converted into carbon atoms during respiration. Nitrogen waste from an organism is converted into usable nutrients for others. The atoms in water molecules are destroyed during a drought. Question 11/22 Which sphere on this Earth has two names and what are they? A. B. C. D. Hydrosphere and Water sphere Biosphere and Human Sphere Atmosphere and Space Lithosphere and Geosphere Question 12/22 Fertilizers are often created using: A. B. C. D. Hydrogen and Nitrogen Phosphorous and Nitrogen Nitrogen and Ammonia Carbon and Nitrogen 2 Unit 1 Test: Environmental Studies Question 13/22 Phosphorous atoms are not often found alone. A. True B. False Question 14/22 Which of the following is NOT a process that drives the carbon cycle? A. B. C. D. Photosynthesis Decomposition Ammonification Cellular Respiration Question 15/22 Which process turns Nitrates back into Nitrogen gas? A. B. C. D. Decomposition Nitrogen Fixation Ammonification Denitrification Question 16/22 Describe using examples from class how climate change is impacting our biodiversity. Ensure you include 3 different ways climate change affect biodiversity and explain why biodiversity is significant (5 marks) (descriptive question) Question 17/22 Explain why our recent increase in population is threatening our Earth by mentioning 3 different human activities that are threatening our biodiversity and biosphere (ie. how does our increase in population threaten our biosphere?) (5 marks) (descriptive question) Question 18/22 Describe the threat of introduced species to a natural habitat. What are the top three dangers that can occur from introduced exotic species to biodiversity (5 marks) (descriptive question) Question 19/22 Describe what you think is the biggest threat to our biosphere today and how you suggest we can make changes to our lifestyle to remedy the stress our biosphere is currently under.
