Across
  1. 1. an organism produces another organism
  2. 4. collection of living matter enclosed by a barrier that separates in from its surrounding.
  3. 5. reproduction/DNA from 2 parents come together to form a new individual
  4. 6. Theory/all living organisms are composed of cells. The cell is the basic unit of life
  5. 9. internal conditions stable
  6. 10. to maintain a constant internal environment in response to environmental changes.
  7. 14. genetic change in a population that is inherited over several generations.
  8. 15. that provide the directions to build a living thing (Genetic Code)
  9. 16. Theory/traits are inherited through gene transmission
Down
  1. 2. from chemical reactions not derived from photosynthesis
  2. 3. in structure, as time passes, from immature to mature
  3. 7. is constant, energy transforms, and some energy is lost during energy transformation
  4. 8. from consumed food(can be measured back to photosynthesis)
  5. 11. from food made from photosynthesis
  6. 12. that a organism responds to
  7. 13. reproduction/DNA from 1 parent creates a new individual
