2. Energy Flow of Organisms

   • Food Chain
     • A chain of organisms in an ecosystem, plus the sun
   • Food web
     • A web of organisms in an ecosystem, plus the sun
   • Energy pyramid
     • A pyramid of consumers in an ecosystem
   • Consumers
     • Decomposers
       • eats dead things
     • herbivores
       • plant eaters
     • Omnivores
       • both plant and meat eaters
     • Carnivores
       • Meat eaters
     • Organisms that eat other organisms for energy
       • Examples
         • Wolves
   • Organisms
     • A living life form, contains alteast one cell
       • Examples
         • Bacteria
   • Producers
     • Producers create their own food for energy
       • Examples
         • Plants

3. Nitrogen Cycle

   • Animals
     • help fertilize the soil the
   • Root systems
     • Roots create nodules that house the bacteria
   • Plants
     • Plants absorb ammonium and nitrate during the assimilation process then converts it into nitrogen.
   • Nitrogen Fixation
     • Any process that that creates nitrogen
   • Bacteria
     • Converts nitrogen gas into solid nitrogen
   • Soil
     • Soil holds the nitrogen deeded for plants to grow
   • Atmosphere
     • holds the gas nitrogen
   • lightning
     • the heat of the lightning can preform nitrogen fixation
   • Decomposers
     • nitrogen in dead things is converted back into gas
   • waste
     • when decomposed it adds nitrogen to the soil

4. Carbon cycle

   • Atmosphere
     • Carbon atoms continually travel from the atmosphere to the ground, then back to thee atmosphere, and so on...
   • Plants and Bacteria on land
     • Converts bicarbonate into organic mollicules
   • Plants and Bacteria in water
     • CO2 dissolves in water, and they make it into organic carbon
   • Animals
     • produce carbon
   • Sedaments and soil
     • Holds the largest preportion of carbon on earth.
   • fossil fuels
     • emit carbon
   • combustion
     • the process of burning fossil fuels
   • decomposition
     • dead animals turned into cerbon with bacteria
   • cellular respiration
     • releases energy in the carbon
   • Photosynthesis
     • turns CO2 into O2

5. water cycle

   • Atmosphere
     • holds precipitated clouds
   • runoff
     • precipitated water flowing down hills, and mountains
   • rivers
     • usually part of runoff, a stream of flowing water usually after precipitation.
   • lakes
     • body of water housing some runoff, and precipitation, and rivers. uses infiltration.
   • ocean
     • very large body of water housing runoff, precipitation and rivers
   • aquifer
     • large rocks holding large amounts of water underground
   • infiltration
     • lake water seeping underground tward the ocean
   • transpiration
     • water evaporating from a plant
   • Exhalation
     • animals peeing
   • evaporation
     • water from the ground turned into a gas
   • precipitation
     • raining water from the sky
   • condensation
     • when evaporated water cools down
