  1. 1. / defined as the way that water moves between being water vapor to liquid water and then back to water vapor.
  2. 3. / An organism, often a bacterium or fungus, that feeds on and breaks down dead plant or animal matter, thus making organic nutrients available to the ecosystem.
  3. 6. / the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
  4. 8. / any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation
  5. 11. / An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis.
  6. 13. / organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter.
  7. 14. / animal that eats both plants and animals for their main food.
  8. 15. web / the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community.
  9. 16. level / each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
  10. 17. / graphical representation in the form of a pyramid showing the feeding relationship of groups of organisms.
  11. 19. / the process by which green plants and certain other organisms transform light energy into chemical energy.
  12. 20. / the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere.
  13. 21. / organism that generally obtains food by feeding on other organisms or organic matter due to lack of the ability to manufacture own food from inorganic sources; a heterotroph.

  1. 2. / the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
  2. 4. / organisms that eat primary consumers for energy.
  3. 5. / animal that gets food from killing and eating other animals.
  4. 7. / a continuous series of natural processes by which nitrogen passes successively from air to soil to organisms and back to air or soil involving principally nitrogen fixation, nitrification, decay, and denitrification.
  5. 8. / organism that feeds on producers.
  6. 9. chain / hierarchical series of organisms each dependent on the next as a source of food.
  7. 10. / animal that gets its energy from eating plants, and only plants.
  8. 12. / he biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP.
  9. 18. / An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy.
