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.

  • 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!)
