Presentation Transcript
a recycling in the biosphere
A. Recycling in the Biosphere
  • 1. Matter is recycled between and within ecosystems.
a recycling in the biosphere1
A. Recycling in the Biosphere
  • 2. Biogeochemical Cycles- Process by which elements, chemical compounds, and other forms of matter are passed from one organism to another, and from one part of the biosphere to another.
b the water cycle
B. The Water Cycle
  • 1. Water moves between ocean, atmosphere and land.
  • 2. H2O molecules enter the atmosphere as water vapor (gas) when they evaporate from the ocean or other bodies of water.
    • Evaporation- Water changes from liquid to gas.
  • 3. Water can evaporate from the leaves of plants also, a process called transpiration.

c nutrient cycles
C. Nutrient Cycles
  • 1. Nutrients- chemical substances an organism needs to stay alive.
  • 2. Every living organism needs nutrients to carry out life functions.

  • 3. The Carbon Cycle
  • The carbon cycle moves carbon from the atmosphere, through the food web, and returns to the atmosphere.
  • Carbon is emitted by the burning of fossil fuels.
  • Some carbon is stored for long periods of time in areas called carbon sinks.

  • 4. The Nitrogen Cycle
  • The nitrogen cycle mostly takes place underground.
  • Some bacteria convert gaseous nitrogen into ammonia through a process called nitrogen fixation.
  • Some nitrogen-fixing bacteria live in nodules on the roots of plants; others live freely in the soil.

  • 4. The Nitrogen Cycle
  • Nitrifying bacteria change the ammonium into nitrate.
  • Nitrogen moves through the food web and returns to the soil during decomposition.

  • 5. The Phosphorus Cycle
  • The phosphorus cycle takes place at and below ground level.
  • Phosphate is released by the weathering of rocks.
  • Phosphorus moves through the food web and returns to the soil during decomposition.

C. Nutrient Cycles
  • 5. The Phosphorous Cycle
  • Phosphorus leaches into groundwater from the soil and is locked in sediments.
  • Both mining and agriculture add phosphorus into the environment.
d nutrient limitation
D. Nutrient Limitation
  • 6. Limiting Nutrient- substance that is scarce or cycles slowly.
  • (This is why fertilizer is used! Contains Nitrogen, Phosphate, Potassium to boost production!)
