Across
  1. 2. respiration The process in cells by which oxygen is chemically combined with glucose to produce energy, carbon dioxide and water
  2. 4. Breaks down dead organisms or the waste of other organisms
  3. 5. The tendency of a cell, organism, or population to maintain internal stability
  4. 8. A structure in a plant cell that contains chlorophyll; sugar molecules are made in chloroplasts through the process of photosynthesis
  5. 10. fuels Fuel such as coal, oil and natural gas; formed over millions of years from the remains of ancient plants and animals
  6. 12. The process by which plants, algae, and some bacteria use sunlight, carbon dioxide and water to make glucose and oxygen
  7. 14. An organism that cannot produce its own food
  8. 15. An organism that obtains nutrients from both plants and animals
  9. 18. An animal that obtains nutrients from eating other animals
Down
  1. 1. An organism that produces its own food
  2. 3. An animal that obtains nutrients only from plants
  3. 6. All the living and nonliving things that interact with each other in an environment
  4. 7. A green pigment that captures light energy for photosynthesis
  5. 9. An organism that can produce food from inorganic materials (e.g., carbon dioxide, sunlight, water)
  6. 11. An organism in a food chain that obtains nutrients from producers or other consumers
  7. 13. A substance that an organism needs to survive and grow
  8. 16. Structures in plant and animal cells that use the process of cellular respiration to transform the energy in food into a form cells can use to carry out their activities
  9. 17. cycle The movement of carbon from the nonliving environment into living things and back
