1. Nutrient Cycles!

2. Diagrams Structured Talk to Text
Use Green /Blue to annotate the diagrams with
Things you know, examples, diagram additions, definitions…
Use Red/Orange to
Write questions
Circle sections you do not understand.
Use Purple to add what is missing!

6. Ecosystem Ecology
Biogeochemical Cycles- the flow of important elements through the ecosystem.
Hydrologic cycle-mainly an abiotically-driven cycle.
Reservoirs-ocean, air, groundwater, glaciers
Assimilation-plants absorb water from the soil, animals drink water and eat organisms
Release-transpiration, evaporation, etc.
Carbon cycle-mainly biotically-driven and tied to atmospheric CO2 levels that cause the greenhouse effect
Reservoirs-atmosphere, fossil fuel, peat, organic material (like cellulose)
Assimilation-photosynthesis, animals eating plants and each other
Release-respiration and decomposition
Nitrogen cycle-also a biotically driven cycle dependent heavily on bacteria
Reservoirs-atmospheric N2, soil (nitrates, nitrites, ammonia)
Assimilation-nitrogen fixation by bacteria, nitrification by bacteria
Release- decomposition of dead organisms and animal waste

7. Which cycle is most affected by human combustion of fossil fuels?
Biotic or Abiotic
Impact Organisms
Into ATM
Out of the ATM
Water
Carbon
Nitrogen
Which cycle is most affected by human combustion of fossil fuels?
When farmers cycle crops they often replace crops such as corn with soybeans. Based on what you know about cycles explain why?

8. smallest living thing living, growing, dividing the base of all life
In your notes, write a haiku about each cycle:
Water, Carbon, Nitrogen
We will record on larger paper and share in 15 minutes.
