  1. Earth’s Cycles of Matter H. Biology Unit 1 Chapter 3-3

  2. Cycles of Matter How do biological systems move energy? • In one direction – it is a one-way flow How do biological systems move matter? • Matter is recycled • Biological systems do not use matter, they TRANSFORM it.

  3. Cycles of Matter CYCLE: A group of processes in which matter and energy move What is a LIMITING NUTRIENT? • When an ecosystem is limited by a single nutrient. • Examples: • Nitrogen – • Farmer’s fields / algal ocean blooms

  4. Carbon Cycle: Carbon is needed as a fuel for life processes. • Nitrogen Cycle:Nitrogen is used to build proteins in cells. • Phosphorous Cycle:Phosphorous is used to build cells. • Water Cycle:Changes in form of water.

  5. Carbon Cycle The Carbon Cycle To Atmosphere: Burning fossil fuel, volcanoes, fires, respiration To Biosphere: Photosynthesis, eating To Hydrosphere: Photosynthesis, eating, runoff To Geosphere: Decomposition of organic matter

  6. The Carbon Cycle To Atmosphere: Burning fossil fuel, denitrification (Nitrates into N2) To Geosphere: Nitrogen fixation (bacteria & lightning)= turns N2 into ammonia, adding fertilizer To Biosphere: bacteria converts ammonia into nitrates/nitrites for producers to make proteins, consumers eat producers To Hydrosphere: Runoff, leaching Nitrogen Cycle

  7. Phosphorous Cycle The Carbon Cycle To Atmosphere: DOESN’T HAPPEN To Geosphere: Runoff, dissolves in water, decomposers To Biosphere: Eating, absorb through roots To Hydrosphere: Runoff, leaching

  8. The Carbon Cycle To Atmosphere: Evaporation, transpiration To Geosphere: Precipitation, condensation, infiltration To Biosphere: Drinking, absorbed through roots To Hydrosphere: Runoff, leaching
