Natural (Nutrient) Cycles

C, N, and P

-macronutrients

(we need a relatively large amount)

carbon cycle 5 processes
Carbon Cycle- 5 processes
  • Respiration -vs- Photosynthesis
  • Decomposition
  • Waste Removal
  • Combustion
  • Metabolism in Organisms
    • Carbohydrates - plants, some animal
    • Proteins - animals, some plants (peanuts)
    • Lipids - animals, some plants (oils)
    • Nucleic Acids - all cells (DNA, ATP)
photosynthesis
Photosynthesis

Carbon “moves” from the atmosphere as carbon dioxide

(CO2) to Plants as sugar (C6H12O6).

respiration
Respiration
  • What happens in respiration?
    • Oxygen - is “gotten” (breathing, for
    • example)
    • Sugar - is obtained(made - plants, eaten -
  • animals)
    • Blood - carries O2 & sugar to all
    • cells
    • Cells - absorb O2 & sugar by
    • diffusion
    • Mitochondria - Makes Energy
    • CO2 - is exhaled/released as waste
nitrogen cycle
Nitrogen Cycle

Importance?

  • Animal and Plants need it (Protein/Nucleic Acid)
  • Plants (and animals) can’t use N gas!

Processes - that put N into a usable form.

Takes place in the Atmosphere & Lithosphere.

  • In Air: Lightning strikes convert N into a usable form
  • Nitrogen Fixation (by bacteria in soil)
    • In soil: Some Bacteria in symbiosis with Legumes
    • In soil: Some bue-green Algae in soil
phosphorus cycle
Phosphorus Cycle

Importance?

  • Plants growth (especially of leaves)
    • >Eutrophication - over growth of algae
  • All cells need it for:
    • DNA - genetics
    • ATP - Cellular Energy

Processes -

Take place primarily in the hydrosphere & lithosphere.

  • Demineralization: phosphorous in rocks is dissolved by ground water
  • Animal/Plant Excretion and Decomposition

Eutrophication

water cycle
Water Cycle
  • Condensation
  • Precipitation
  • Evaporation
  • Respiration
  • Evapotranspiration
  • Infiltration
  • Run-off
summary
Summary
  • C - needed for “backbone” of all organic chemicals.
  • N - proteins, nucleic acids
  • P - nucleic acid / plant growth
  • Water - 75% of organisms / Earth
  • All (nutrients) are recycled according to The Law of Conservation of Matter.
