Across
  1. 2. cycle - sulfur circulates through the biosphere in the _______
  2. 4. - use some of the ammonia they produce as a nutrient and excrete the rest to the soil or water
  3. 10. algae - produce large amounts of volatile dimethyl sulfide, or DMS
  4. 11. - it release the carbon stored in the bodies of dead organisms on land back into the air as CO2.
  5. 13. - circulates through water, the earth's crust, and living organisms in the phosphorus cycle
  6. 14. sulfide - a colorless, highly poisonous gas with a rotten-egg smell.
  7. 15. overload - it is a serious and growing local, regional, and global environmental problem that has attracted little attention
  8. 18. - the primary sculptor of the earth's landscape
  9. 20. cycle - connect past, present, aand future forms of life.
  10. 21. cycles - It is the elements and compounds that make up nutrients move continually through air, water, soil, rock and living organisms in ecosystems and in the biosphere in cycles.
Down
  1. 1. - it can be lost from the cycle for long periods when it washes from the land into streams and rivers and is carried to the ocean
  2. 3. - it is the major reservoir for nitrogen
  3. 5. - about 90% of the water that reaches the atmosphere evaporates from the surfaces pf plants through a process called?
  4. 6. producers - it remove CO2 from the atmosphere and aquatic producers remove it from the water
  5. 7. gas - it can warm the atmosphere and deplete stratospheric ozone, which keeps most of the sun's harmful ultraviolet radiation from reaching the earth's surface
  6. 8. - it is a crucial component of proteins, many vitamins, and nucleic acids as DNA
  7. 9. vegetation - can also alter wether patterns by reducing transportation
  8. 10. boots biology - field research, sometimes called ______, involves observing and measuring the structure of natural ecosystems and what happens in them.
  9. 12. - the basic building block of the carbohydrates, fats, proteins, DNA, ands other organic compounds necessary for life.
  10. 16. information systems - provide the computer technology for storing, organizing, and analyzing complex data collected over broad geographic areas.
  11. 17. cycle - also know as water cycle that collect, purifies, and distributes the earth's fixed supply of water.
  12. 19. - in oxygen-consuming producers, consumers and decomposers then carry out aerobic respiration
