front 1 What is the effect of the biogeochemical cycles? | back 1 recycling matter through the biosphere |
front 2 The ocean and the atmosphere serve as long-term storage areas for carbon and other nutrients. What are these storage areas called? | back 2 reservoirs |
front 3 Which process allows water to enter the atmosphere? | back 3 evaporation |
front 4 What is the name of the process that plants use to remove carbon dioxide from the atmosphere? | back 4 photosynthesis |
front 5 Which process plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus? | back 5 decomposition |
front 6 Why are bacteria a necessary part of the nitrogen cycle? | back 6 Other living things cannot use atmospheric nitrogen. |
front 7 The phosphorus cycle differs from the biogeochemical cycles in that | back 7 it does not have an atmospheric reservoir. |
front 8 Thiobacillus denitrificans is a species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as nitrogen in its environment. It is used in bioremediation (natural cleansing) of groundwater that contains excess nitrate, allowing the nitrates to be removed. Through what process does Thiobacillus denitrificans help bioremediate groundwater? | back 8 Denitrification |
front 9 Which are limiting nutrients for plant growth? | back 9 phosphorus and nitrogen |
front 10 Which of these nutrients can be found in all organic compounds? | back 10 Carbon |
front 11 What would happen if there were no condensation stage in the water cycle? | back 11 Water could not convert from a gas to a liquid. |
front 12 Actinobacteria sp. are fermenting organisms, which do not require oxygen to survive. These organisms break down organic material and convert it to inorganic material. Which part of the carbon cycle does this describe? | back 12 Decomposition |
front 13 Which of the following would be a result of eutrophication of a lake? | back 13 hypoxia, or low levels of oxygen |
front 14 Osteoporosis is a disease that affects the bones and leads to an increase in bone fractures. Osteoporosis is most likely to be affected by which cycle? | back 14 Phosphorus |
front 15 Which statement best describes a human influence on the biogeochemical cycles? | back 15 increased eutrophication caused by high levels of nitrogen and phosphorous |
front 16 Which best describes a possible negative impact of irrigation of farmland? | back 16 Increased runoff can pollute bodies of water. |
front 17 What process adds carbon dioxide to the air? | back 17 Respiration |
