TRANSCRIPT
Label each organism in the above food web: producer, primary consumer, secondary consumer, Tertiary consumer, herbivore, carnivore, omnivore.
Starter 10-2-081. Name abiotic factors that get cycled
through ecosystems.2. Name the cycles that you know and describe
them.
Starter1. Name the 5 abiotic factors that get cycled through
ecosystems.
2. Name the 4 cycles we talked about.
3. How do animals and plants support life for each other? Name the two processes.
4. List what puts CO2 into the atmosphere. What takes it out?
5. Describe three roles that bacteria play in the nitrogen cycle.
6. Starting with N2, explain where it goes and what does the cycling along the way.
7. Starting with a snowflake. Explain the water cycle.
8. How does the phosphorous cycle differ from the other cycles (2 ways)?
9. Why is the phosphorous cycle necessary?
Cycles3 steps
Producers abiotic factors organic compoundsConsumers Producers then… #1 and #2Decomposers inorganic raw materials
WaterCarbon – oxygenNitrogenPhosphorous
By the end you will be able to diagram and explain them.
Water – Who are the actors?Ground Water
H2O found in the groundEvaporation
Liquid Gas Warm
Transpiration Liquid gas from plants
Water Vapor Gaseous H2O
Condensation Gas liquid Cold
Precipitation Water returning to the ground
Rain, sleet, snow, hail, etc…Runoff
Precipitation that is not absorbed and runs off into a ground water source
Carbon and Oxygen – Living Players
ProducersOrganic compounds from inorganic supply
Photosynthesis CO2 + H2O Suns energy C6H12O6 + O2
Recycled via Cellular Respiration
C6H12O6 + O2 CO2 + H2O Decomposition
Carbon and Oxygen – Nonliving Players
Fossil fuelsCO2
Burning of WoodNaturalHuman
Geologic EventsVolcanic eruptions
Cellular Respiration and
Decay
PhotosynthesisCO2
in Atmosphere
Combustion of fossil fuels
Volcanoes
Forest Fires
Fossil Fuels
Cellular Respiration and Decay
NitrogenAmino acids, proteins, nucleic acidsAtmosphere ~80% Nitrogen (N2)
Not helpful Can’t use N2 gas
If not N2, then what?Ammonium (NH4+) Nitrate (NO3-)
How do we get there?
Nitrogen CycleN2 in the atmosphere
1.Nitrogen fixation Bacteria N2 Ammonia (NH3)
Found in the soil Picks up a H to create Ammonium (NH4+)
2.Nitrification Bacteria NH4+ nitrates (NO3-)
Producers ammonium (NH4+) and nitrates (NO3-)Consumers N in organic moleculesDecomposers wastes and decaying bodies ammonium
(NH4+) back to the soil
3.Denitrification Bacteria nitrates (NO3-) N2
Phosphorous Cycle
Nucleic Acids, cell membranes, ATP, ect…Doesn’t occur in the atmosphereFound only as PO4
3- Decomposition
Waste and dead organismsWeathering of rocksFertilizers
Phosphorous CyclePlants
Absorb free inorganic PO43- in the soil or water
Create organic compoundsConsumers
Eat producers and create organic compounds from by breaking down plant tissues
DecomposersBreakdown waste and dead organisms
Releases inorganic PO43- back into the water or soil
Assimilation by plant cells
Weathering of rock
Phosphates in soil
Phosphates in solution
Decomposition by fungi and
bacteria
Urine
Animal tissues and feces
Plant Tissues
Loss in drainage
Incorporation into sedimentary rock; geologic uplift moves this rock into terrestrial
environments
Starter 1-22-081. Explain how photosynthesis and respiration
are involved in cycling carbon and oxygen.2. List what inputs CO2 into the atmosphere.
3. Describe three roles that bacteria play in the nitrogen cycle.
4. Starting with N2, explain where it goes and what does the cycling along the way.
5. Follow a raindrop through one possible path through the water cycle, ending as it is today, snow!!
