  1. 2. - All the organisms genetically similar enough to breed and produce live, fertile offspring in nature.
  2. 3. In biology, organisms that consume carrion, or organisms not killed by the scavenger.
  3. 5. Organisms that only eat plants
  4. 6. Law of Thermodynamics that states that, with each successive energy transfer or transformation in a system, less energy is available to do work
  5. 10. The accumulated biological material produced by living organisms.
  6. 11. Organisms that eat both plants and animals.
  7. 12. The capacity to do work, such as moving matter over a distance.
  8. 14. Step in the movement of energy through an ecosystem; an organism’s feeding status in an ecosystem
  9. 18. Organisms that mainly prey upon animals.
  10. 20. The biochemical process by which green plants and some bacteria capture light energy and use it to produce chemical bonds. Carbon dioxide and water are consumed while oxygen and simple sugars are produced.
  11. 22. Organisms that synthesize food molecules from inorganic compounds by using an external energy source; most producers are photosynthetic.
  12. 23. The process in which a cell breaks down sugar or other organic compounds to release energy used for cellular work; may be anaerobic or aerobic, depending on the availability of oxygen.

  1. 1. Organisms that consume organic litter, debris, and dung
  2. 4. Fungus or bacterium that breaks complex organic material into smaller molecules
  3. 7. Potential energy stored in chemical bonds of molecules.
  4. 8. Energy contained in moving objects, such as a rock rolling down a hill, the wind blowing through the trees, or water flowing over a dam
  5. 9. A complex, interlocking series of individual food chains in an ecosystem
  6. 13. Photosynthesizing organisms.
  7. 15. All members of a species that live in the same area at the same time.
  8. 16. A measure of disorder and usefulness of energy in a system.
  9. 17. Extracting energy for life from inorganic chemicals, such as hydrogen sulfide, rather than from sunlight
  10. 19. Law of Thermodynamics that states that energy is conserved; that is, it is neither created nor destroyed under normal conditions
  11. 20. The amount of biomass (biological material) produced in a given area during a given period of time.
  12. 21. Organism that obtains energy and nutrients by feeding on other organisms or their remains
  13. 22. Stored energy that is latent but available for use. A rock poised at the top of a hill and water stored behind a dam are examples of potential energy.
