POOP LOOP LAB (Chemistry (nitrogen cycle (Very important because its…

- - - - DNA
      - Proteins
      - Chlorophyll in plants
    - - Consumers eat these plants get nitrogen
      - Mostly absorbed through the water.
        
        Usually the essential elements are taken up as a positively charged cation or a negatively charged anion
        
        Need certain Bacteria to convert the nitrogen to usable forms
        
        They Use
        
        Ammonium (NH4+)
        
        Nitrite (NO2-)
        
        Nitrate (NO3-)
        
        Nitrogen fixing bacteria
        Nitrifying bacteria
        
        Legumes are also nitrogen fixers
    - - not usable
      - Usable Forms-NH4+, NO3-, NO2-
- - - - Single Parent
      - Genetically identical
      - Potatoe
      - Cell division
    - - The plant must be Pollinated-Pollen from the male part of a flower travels to the female part of another flower where the seeds are made.
        
        Seeds are then created and spread in various forms such as being eaten and then pooped back into environment
        
        Germination- process where the seed grows into plant
        
        Seeds need moisture, warmth, nutrient rich soil, sunlight, and a good quality seed
        
        Seeds=embryos with a seed coat and food store
      - Some are sexual and some are asexual
    - - A male sperm fertilizes a female egg and creates an embryo
      - Sexual Reproduction
    - - Two parents
      - 50/50 Genetic Information
      - Humans
      - Cells multiple
- - - - Most of human mass comes from
        
        carbon, hydrogen, oxygen, nitrogen, phosphorus, and calcium
        
        These are used to make
        
        carbohydrates, nucleic acids (DNA/RNA), proteins
    - - Need polyatomic ions
        
        The key three being NPK:
        
        nitrogen (N), phosphorus (P) and potassium (K).
    - - Salmon Carcass
        
        Eaten by scavengers
        
        Scavenger feces deposited in forest
        
        Marine-derived nutrients enter soil
        
        Nutrients taken up
        by vegetation through roots
        
        Herbivores feed on vegetation
        
        Scavenger hauls carcass into forest
