  1. Snakes can too ski! I seen it on YouTube E=MC Hamster Gravity is Just a myth! Now Go Jump off a Roof. (Don’t really Do That!) Thotophnthiffis Dogs (It’s my favorite Floyd tune) 100 100 100 100 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500

  2. What is the source of light energy that essential for photosynthesis?

  3. The SUN!

  4. In the carbon cycle, when we say “energy” what molecule are we referring to?

  5. Adensosine Triphosphate Aka… ATP

  6. What molecules are required for cells to undergo respiration (what are the reactants)? How do animals get the carbon that they need?

  7. O2=Oxygen & C6H12O6=Glucose From Eating Plants(or animals that eat plants.

  8. How does nitrogen get into the atmosphere from the biotic world?

  9. Organisms die and certain bacteria release the nitrogen as free N2.

  10. What are the products of respiration?

  11. Water, Carbon Dioxide, and Energy (ATP)

  12. What is succession (generally speaking)?

  13. The gradual development of a community over time

  14. What is primary succession?

  15. The process by which an area with no biotic elements develop a community over time (starting with the formation of soil).

  16. What is a pioneer species?What is a climax species?

  17. Pioneer: The an organism that is the first to inhabit a previously uninhabitable area. Lichen is one example.Climax: Slow growing and well-adapted. Hardwood Trees (oaks, maples) are examples.

  18. How is secondary succession different than primary succession?

  19. Secondary succession occurs in an area where some event (natural or human…like a fire maybe?) has destroyed the pre-existing community.Also…there is already soil present where secondary succession occurs…not so for primary succession.

  20. What happens to the nitrogen that you breathe in?

  21. Nuthin’!You can’t use free nitrogen (N2) and neither can other animals or plants. Plants and animals need fixed nitrogen.

  22. What is fixed nitrogen and where does it come from?

  23. Well…free nitrogen is absorbed by plants and then nitrogen fixing bacteria convert it to a form that’s usable for plants and animals. Nitrogen fixing bacteria also exist in soil and in water.Lightning can also fix nitrogen.

  24. Why is nitrogen important to living things?

  25. Nitrogen is important for making things such as amino acids (for making proteins) and nucleotides (in DNA and RNA).

  26. What are stages in the water cycle?

  27. Evaporation: Liquid to gasCondensation: gas to liquidPrecipitation: atmosphere to EarthTranspiration: ground to plants/animals to atmosphere

  28. Why are these cycles (nitrogen, carbon, and water) called cycles anyway?

  29. They involve the continuous movement of substances from the biotic (living) world to the abiotic (non-living) world.

  30. Where do photosynthesis and cellular respiration mostly occur?

  31. Photosynthesis: ChloroplastsCellular Respiration: Mitochondria

  32. What types of organisms can undergo photosynthesis?

  33. Plants, algae, & cyanobacteria.

  34. What is the name of the pigment involved in photosynthesis that captures the energy from sunlight?

  35. Chlorophyll

  36. What is happening during photosynthesis…generally speaking?

  37. Plant cells are making food from sunlight (carbon dioxide and water are also necessary).

  38. What is the formula for photosynthesis?

  39. sunlight 6CO2 + 6H2O C6H12O6 + 6O2Reactants Products

  40. Why do heterotrophs (like us) depend upon photosynthesis to survive?

  41. Photosynthetic autotrophs (plants and algae) are the base of almost all food webs and energy pyramids. They also produce oxygen, upon which we are dependent.

  42. What is happening during cell respiration, and where do the organisms doing this get the raw materials to make it happen?

  43. Animal and plant cells are producing energy (ATP) from food (glucose). The animals get food from eating things, and the plants make their own food using photosynthesis. Animals take in the oxygen needed by breathing, and the plants take in oxygen when sunlight isn’t present.

  44. What is the equation for cell respiration?

  45. C6H12O6 + 6O2 6CO2 + 6H2O + Energy(Glucose) (ATP)Reactants Products

  46. How are the equations for photosynthesis and respiration related?

  47. They are opposites (not exact…but close)! The reactants (raw materials) for one are the products of the other.

  48. What is happening in photosynthesis…generally speaking?

  49. Most plants, cyanobacteria, and algae make food (glucose) from energy (ATP).

  50. What is happening in cellular respiration?
