  1. 7. The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter to sustain the organism’s life functions.

  3. 11. Organisms that break down the dead remains of other organisms.
  4. 12. Organisms that eat only plants.
  5. 14. A theory that has been tested by and is consistent with generations of data.
  6. 16. The sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and structures necessary for life.
  7. 18. The process by which physical and biological characteristics are transmitted from the parent (or parents) to the offspring.
  8. 19. An abrupt and marketed change in the DNA of an organism compared to that of its parent.
  9. 22. Organisms that eat both plants and other organisms.
