Across
  1. 4. sphere of all the water on earth
  2. 5. Type of organism that is able to make its own food,base of the food chain
  3. 6. Describes a situation in which oxygen is present
  4. 10. Third step of aerobic respiration, NADH, fadh2 from earlier reactions are used to make 32 units of atp
  5. 15. Nutrient, forms the backbone for all macromolecules in living things
  6. 19. Type of organism that breaks down biotic compounds into abiotic compounds, recyclers
  7. 20. sphere of all the gases surrounding earth
  8. 22. Second step of anaerobic respiration, 2 types include alcoholic and lactic acid
  9. 23. Organelle-site of photosynthesis
  10. 24. sphere of all living things on earth
  11. 25. Substances at the beginning of a chemical reaction, changed into products
  12. 26. Type of organism that must eat other organisms to obtain energy
  13. 27. Nutrient, used in proteins and nucleic acids, must be 'fixed for living things to use, often limited
  14. 28. Describes a situation in which oxygen is not present
Down
  1. 1. Second step of photosynthesis, uses energy in ATP and nadph to make glucose from co2
  2. 2. First step of photosynthesis, uses sunlight to split water and make ATP and nadph, oxygen is released
  3. 3. Process of using light energy to make glucose, starts with carbon dioxide and water and ends with glucose and oxygen
  4. 7. First step of aerobic respiration, breaks down glucose into pyruvate, make some nadh
  5. 8. Process of breaking down glucose to make ATP, starts with glucose and oxygen and ends with carbon dioxide and water
  6. 9. Adenosine triphosphate, charged energy storage molecule with 3 phosphorus groups
  7. 11. Adenosine diphosphate, uncharged energy storage molecule with 2 phosphates
  8. 12. Substances created during a chemical reaction, made from reactants
  9. 13. Nutrient, used in phosphates of Nucleic Acids and phospholipids of membranes, often limited
  10. 14. Pigment used in chloroplasts, used to trap light energy during photosynthesis
  11. 16. Second step of aerobic respiration, pyruvate is broken down while nadh and fadh2 are made, releases co2
  12. 17. Organelle, site of steps 2 and 3 of aerobic cellular respiration
  13. 18. sphere of all the soil and rocks on earth
  14. 21. Anything that has mass and takes up space, makes up everything
