,Earth's Surface Water
71% water
NOT all is drinkable
ninety seven% of water is MARINE
3% of water is FRESH
Elements that make up water
1. Oxygen (partially poor)
2. Hydrogen (partially effective)
Polarity
Atoms oxygen & hydrogen have an unequal sharing of electrons in water molecules
WATER dissolves more materials than any over liquid
Partial price attracts different polar molecules to dissolve them
Cohesion
Water sticks to itself
Surface anxiety
Water Droplets
Adhesion
Water sticks to other things
Capillary Action: facilitates draw water up the plant
Transpiration
Evaporation of water from the leaves of a plant; water molecules "pull" every other up in
opposition to gravity because of concord & adhesion
Capillary Action
Water actions UP stem in xylem tissue machine
Epiphytes
Plant or plant-like organism that grows at the surface of every other plant, deriving moisture
and vitamins from the air, rain, water or debris gathering round it
,Macronutrients
1. Nitrogen
2. Phosphorous
three. Sulfur
four. Potassium
5. Calcium
6. Magnesium
Bedrock
Underlying geology (distinctive minerals/vitamins in line with rock)
Soil Posterity
Different kinds & sizes of soil maintain vitamins higher
Nutrients: Clay/organic depend
Poor nutrient availability
Desert/Lake
Adaptations for Plants for Nutrients
1. Root allocation
2. Succulent Leaves/Waxy
3. Carnivory
4. Spines/Hairs
Adaptations for Animals for Nutrients
1. Mechanistic:
EX: seabirds steady excess vitamins thru nasal cavity
2. Resource Partioning: adapting to a meals source with little opposition
3. Metabolic: EX: marine fish excrete little freshwater, freshwater fish secrete large amounts
of water
Photosynthesis
Conversion of inorganic CO2 into organic compounds the use of water and light power
Photosynthesis Equation
6CO2 + 6H2O ------> C6H12O6 + 6O2
Plants have specialized molecules that take in some light wavelengths
, Plants soak up a few light however reflect green and yellow mild
"Action Spectrum": blue and red
Closed Energy System
Nutrients cycle WITHIN the Earth
1. Nutrient Cycle
2. Water Cycle
Open Energy System
Energy flows to AND from the Earth
1. Flow of energy from the SUN
Energy INputs vs OUTputs
Inputs come from the solar
Outputs radiate from the Earth
First Law of Thermodynamics
"Energy cannot be created or destroyed; it may only trade form"
Where does maximum photosynthesis arise?
Marine ecosystems (phytoplankton)
Autotrophs use photosynthesis!
Only 1% of daylight is absorbed through flora
Producers (Plants)
Primary Consumer (Herbivore)
Secondary Consumer (Carnivore)
Decomposers (Insect, Bacteria)
Trophic Levels
Level in a meals chain
(Producers are continually at the "backside" of the food chain)
Heterotroph
All non-manufacturers/different organisms that advantage strength with the aid of consuming
different organisms
