  1. 3. animals that eat producers (plants).
  2. 6. any heritable trait that improves the ability of an individual organism to survive and reproduce at a higher rate that other individuals in a population.
  3. 7. a group of organisms that have distinctive traits and can reproduce fertile offspring.
  4. 8. the living biological parts of an ecosystem (plants and animals).
  5. 9. the process whereby earth's life changes overtime though changes in the genetic characteristics of populations.
  6. 11. the highest rate at which a renewable resource can be used indefinitely without reducing its available supply.
  7. 12. can eat plants and other animals.
  8. 14. the 3 principles of sustainability are Biodiversity, Solar energy, and _______.
  9. 18. exist in an infinite quantity.
  10. 20. is the natural resources and natural services that keep us and other forms of life alive and support our economies natural resources.
  11. 21. also know as self feeders or autotrophs because they make the nutrients they need.
  12. 22. feed on the wastes or dead bodies of other organisms.
  13. 23. the nonliving parts of an ecosystem (water, air, rocks).
  14. 24. is contamination of the environment by a chemical or other agent such as noise or heat.
  15. 25. animals that feed on the flesh of other animals (meat eaters).
  16. 26. mineralized or petrified replicas of skeletons, bones, teeth, shells, leaves, and seeds, or impressions of such items found in rocks.
Down
  1. 1. random changes in the DNA molecules of a gene in any cell.
  2. 2. process of obtaining energy used by most producers which involves capturing light and turing it into energy.
  3. 4. theory that states that all species descended form earlier, ancestral species.
  4. 5. are materials and energy in nature that are essential or useful to humans.
  5. 10. is the variety of the earth's species, the genes they contain, the ecosystems in which they live and the ecosystem processes of energy flow and nutrient cycling that sustain all life.
  6. 13. the biological science that studies how organisms, or living things, interact with one another and with their environment.
  7. 15. the fundamental structural and functional unit of life.
  8. 16. process in which individuals with certain traits are more likely to survive and reproduce under a particular set of environmental conditions.
  9. 17. also called consumers because they obtain their energy by consuming other organisms.
  10. 19. populations of different species living in a particle place, and potentially interacting with each other.
  11. 22. are consumers that release nutrients from the dead bodies of plans and animals and return them to the soil, water, and air.
