26. Carbon cycle • Name 3 ways carbon can enter the atmosphere.

27. Carbon cycle • Name 3 ways carbon can enter the atmosphere. Cellular respiration, burning fossil fuels, burning trees, volcanoes, etc.

28. Nitrogen cycle • Where is the biggest nitrogen reservoir?

29. Nitrogen cycle • Where is the biggest nitrogen reservoir? The atmosphere is 78% nitrogen.

30. Nitrogen cycle • Explain what will happen when legumes are planted in a grassland ecosystem. • Why will it happen?

31. Nitrogen cycle • Explain what will happen when legumes are planted in a grassland ecosystem. Nitrate level will increase • Why will it happen? Legumes have nodules that provide a home for bacteria which fix nitrogen

32. Phosphorus cycle • Is there a gas phase in the phosphorous cycle? Phosphorous is a limiting factor in aquatic systems. How could adding phosphorous to a lake decrease biodiversity of the lake?

33. Phosphorus cycle • Is there a gas phase in the phosphorous cycle? No Phosphorous is a limiting factor in aquatic systems. How could adding phosphorous to a lake decrease biodiversity of the lake? Eutrophication and could cause species adapted to low phosphate levels to become extinct.

35. What does deforestation do to the nutrient levels of streams that receive runoff from deforested areas? Nutrient levels increase initially.

36. What is the difference between ecosystem resilience and ecosystem resistance?

37. What is the difference between ecosystem resilience and ecosystem resistance? Resilience how fast an ecosystem comes back after a shock, and resistance is how hard a shock an ecosystem can take before it changes.
