What to Focus On

  • Nutrient cycles are biogeochemical cycles.
  • Three nutrient pools are reservoir, exchange, and biotic pools.
  • Nutrients move from the environment into producers, then through food chains, and back through decomposition.
  • Carbon moves between the atmosphere, organisms, soil, and oceans.
  • Photosynthesis removes carbon dioxide from the atmosphere.
  • Respiration and decomposition return carbon dioxide to the atmosphere.
  • Certain bacteria convert atmospheric nitrogen into ammonia.
  • Nitrification produces nitrites and then nitrates.
  • Plants absorb nitrates readily.

Common Mistakes to Avoid

Nutrient cycles are just the movement of nutrients in one direction from soil to plants.

The reservoir pool is the most active pool because it stores the nutrients.

The carbon cycle and nitrogen cycle are the same because both involve gases in the atmosphere.
