Biogeochemical Cycles


Biogeochemical cycles

Water

Cycle

  • Defined: Movement of water through the atmosphere

  • 75% of the earth is water

  • 99% of water undrinkable (salty & frozen)

  • Water recycles over and over


Biogeochemical cycles

How Does Water Go Up?

  • Water rises into the atmosphere in two ways:

    • Evaporation: Heat changes water from a liquid to a gas

    • Transpiration: Water evaporates from the leaves of plants through openings called stomata


Biogeochemical cycles

How Does Water Come Down?

  • Warm, moist air rises and eventually cools

    • Condensation: process where water vapor turns into a liquid

  • Rain, snow, sleet, or hail falls when water drops become heavy (Precipitation)


Biogeochemical cycles

Runoff: Water runs down hill into rivers, lakes, streams, oceans…

Infiltration: Water soaks into the soil and collects as groundwater

Process repeats

Water on the Ground


Animation challenge whose water cycle animation is better some guy on the internet or mr kobe s

Animation ChallengeWhose water cycle animation is better?Some guy on the Internet???OrMr. Kobe’s??


Water evaporates and rises

Animation #1

Water evaporates and rises


Condensation clouds forms

Animation #1

Condensation: Clouds forms


Precipitation water falls rain snow sleet or hail

Animation #1

Precipitation: Water falls(rain, snow, sleet, or hail)

Oxygen cycle

Oxygen Cycle

  • Autotrophs: Release O2 into atmosphere via photosynthesis

  • All life: Absorbs O2 to be used during cellular respiration

    • Respiration: creates ATP energy for cells

O2

O2


Carbon cycle

Carbon Cycle

CO2

  • Carbon = (organic molecules) carbohydrates, proteins, lipids, nucleic acids

  • Plants & autotrophs:

    • Intake: Absorb CO2 from atmosphere

      • Create glucose & sugar via photosynthesis

    • Output: Release CO2 during respiration

CO2


Carbon cycle1

Carbon Cycle

  • Consumers

    • Intake: Carbon moves up the food chain as 1 feeds on another

    • Output: Release CO2 during respiration

CO2

Carbon cycle2

Carbon Cycle

  • Decomposers

    • Input: Feed on dead organic matter

    • Output: Release CO2 during respiration

    • Output: Organic molecules returned to soil during decomposition

Carbon cycle3

Carbon Cycle

  • Human Industry

    • Output: Release CO2 into atmosphere when fossil fuels (coal, oil, natural gas) are burned

CO2


Nitrogen cycle

Nitrogen Cycle

N2

  • N = 78% atmosphere (most unusable)

  • Soil Bacteria

    • Nitrogen fixation: convert atmospheric nitrogen into ammonia

    • Nitrification: ammonia converted into nitrates

Ammonia

Nitrates


Nitrogen cycle1

Nitrogen Cycle

  • Plants

    • Absorb nitrates through their roots

Nitrates


Nitrogen cycle2

Nitrogen Cycle

  • Animals

    • Ingest nitrates through the food chain (plants eaten)

Nitrates


Nitrogen cycle3

Nitrogen Cycle

  • Decomposers

    • Return ammonia to soil by feeding on dead matter

Ammonia

Ammonia

Ammonia


Nitrogen cycle4

Nitrogen Cycle

  • Lightning

    • Energy breaks atmospheric nitrogen into Nitrogen oxide

    • Nitrogen oxide falls in rain to soil


Phosphorus p cycle

Phosphorus (P) Cycle

  • No phosphorus in atmosphere

  • Rocks

    • Phosphorus released by weathering of rocks

P

P


Phosphorus p cycle1

Phosphorus (P) Cycle

  • Plants

    • Absorb P into their roots

P


Phosphorus p cycle2

Phosphorus (P) Cycle

  • Animals

    • Ingest P when plants eaten

    • P continues to move up food chain

P


Phosphorus p cycle3

Phosphorus (P) Cycle

  • Decomposers

    • Breakdown dead matter and release P into soil

P

P

  • Human Contribution

    • Adding excess P from fertilizers

    • P washes into lakes, etc…

    • Excess P causes extreme algae growth

Kobe Kuiz

  • Name and define the 6 stages of the water cycle.

  • How is oxygen released into the atmosphere?

  • In which cellular process is oxygen removed and used from the atmosphere?

  • Which organic molecule is created by photosynthesis?

  • In which cellular process is carbon dioxide released into the atmosphere?

  • How are humans disrupting the carbon cycle?

  • How does nitrogen fixation and nitrification differ?

  • How do plants obtain nitrogen?

  • Which objects release phosphorus over time?

  • How are humans disrupting the phosphorus cycle?
