Poop Loop Lab (Ecology (Nitrogen Cycle (Nitrogen can be stored in:…

- - - - All the mass of the human body is made up of 6 elements
        
        Carbon
        
        Nitrogen
        
        Oxygen
        
        Hydrogen
        
        Phosphorous
        
        Calcium
      - There are 17 essential element for plants
        
        3 of the key nutrients are nitrogen (N), phosphorus (P), potassium (K)
        
        Commercial fertilizers are labeled with a NPK ratio
  - - - Salmon gets eaten by predators, predators takes salmon into forest to eat
        
        Scavengers feed on salmon carcass
        
        Feces from salmon-eating-animals gets deposited in forest
        
        Marine derived nutrients enters soil
        
        Nutrients taken up by vegetation
        
        Herbivores eat vegetation

  - - - Nitrogen fixing bacteria
        
        Nitrogen gas > ammonium
      - Nitrifying bacteria
        
        Ammonium > Nitrite > Nitrate
      - The roots of legumes houses rhizobia that contains nitrogen fixing and nitrifying bacteria
    - - Oceans and marine sediments
      - Living organisms
      - Soil
      - Atmosphere
        
        Nitrogen makes up 78% of the atmosphere
- - - - Seeds
        
        Seeds are made when the pollen from the male part of the flower travels to the female part of the flower
      - Gamete + Gamete = Zygote
    - - Advantages
        
        No energy spent finding mate
        
        Population expands quickly
      - Disadvantages
        
        No genetic variation
        
        Natural selection is not possible
      - All offspring are clones of parents
      - Only requires a single parent
      - Asexual reproduction in plants is called vegetative propagation
- - - - They will bond with other ions with the opposite charge; ionic compounds with polyatomic ions are neutral
