24. Figure 6.6: explained the direction of arrows in the diagram.- the arrow is point towards the energy transfer. For example, hyenas eat grass, so the energy is being transferred from grass to hyena 25. Give an example of an omnivore- grizzly bear 26. Give an example of a scavenger- vulture 27. Give an example of detritivores- dung beetles 28. Describe how scavengers, detritivores, and decomposers are important to an ecosystem.- decomposers break down the dead organisms to give energy back to the producers, detrivores break down the waste products in the dead organisms and scavengers consume the dead animals 29. Figure 6.6: Identify two omnivores and describe their different trophic levels within the ecosystem. Omnivores- zebra, hyena. They are both primary consumers Some ecosystems are more productive than others 30. What does the amount of energy in an ecosystem determine? 31. Show the equation for net primary productivity (NPP). 32. Explain gross primary productivity (GPP) and net primary productivity (NPP) in terms of a paycheck. 33. How can scientists measure CO 2 movement during photosynthesis? Write the equation. 34. How can scientist drive gross primary productivity (GPP)? 35. Figure 6.7: draw and color code the diagram. 36. Figure 6.7: why is converting sunlight into chemical energy an inefficient process? 37. Figure 6.7: where does the 99% of unused sunlight go? 38. Of the 1% of the sun's energy that is captured, what percent is used to support the producer's growth and reproduction? 39. How much carbon will plants in one square meter of forest in North America add to their tissues every year? 40. What factors determine where producers grow best? 41. Figure 6.8: identify the ecosystems with the greatest amount of net primary productivity and the ecosystems with the lowest amount of net primary productivity. The efficiency of energy transfer affects the energy present in each trophic level 42. Explain the difference between standing crop and productivity. Given example. 43. How much is the average ecological efficiency? 44. Figure 6.9: explain how the numbers change in the trophic pyramid. 45. Figure 6.9: explain why the lion does not receive all 1000 joules of energy from the zebra. 46. What does the principle of ecological efficiency imply about the human diet? 47. Explain why more land is needed for humans to consume beef than is needed for humans to consume soybeans. 48. Finish this statement: "When we act as primary consumers, we require..."
