SOLVED - Elaborated AP Environmental Science-Unit 1 Version 2-2023 What are nutrients and why are they important? - Ans | The elements and compounds that organisms need to live, grow, and thrive 2. Biogeochemical Cycles - Ans | The movement of abiotic factors between the living and nonliving components within ecosystems; also known as nutrient cycles (i.e., water cycle, carbon cycle, oxygen cycle, and nitrogen cycle). 3. The Water Cycle - Ans | Evaporation, condensation, precipitation, run off, transpiration, infiltration. Humans impact this by storing water in reservoirs, irrigation, deforestation, and putting chemicals in it 4. Condensation - Ans | The change of state from a gas to a liquid 5. Run off - Ans | The draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc. 6. Transpiration - Ans | Evaporation of water from the leaves of a plant 7. Infiltration - Ans | Flow of water from the land surface into the subsurface 8. The Carbon Cycle - Ans | The organic circulation of carbon from the atmosphere into organisms and back again. Humans impact this by burning fossil fuels and cutting down trees, 9. The Nitrogen Cycle - Ans | The transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere. Humans impact this by altering the amount of nitrogen that is stored in the biosphere. 10. The Phosphorus Cycle - Ans | The movement of phosphorus atoms from rocks through the biosphere and hydrosphere and back to rocks. 11. The Sulfur Cycle - Ans | Cyclic movement of sulfur in various chemical forms from the environment to organisms and then back to the environment. Humans impact this by burning coal, natural gas, and other fossil fuels which greatly increases the amount of sulfur in the atmosphere and ocean and depleted the sedimentary rock sink 12. Where are the four major areas of water storage on Earth? - Ans | Atmosphere, surface water, ground water, and living things 13. Ecology - Ans | Study of how organisms react with each other and the non-living environment 14. Abiotic Factors - Ans | Nonliving components of environment.
