Poop loop lab (Chemistry: # (Lesson 2: (Polyatomic ions: (What are…

- - - - What are polyatomic ions: They are called many atom ions and are bonded through covalent bonds with an uneven number of protons and electrons meaning they create a net charge.
      - How do they act like other ions: They will form bonds of the opposite charge and Ionic compounds with polyatomic ions are neutral just like binary compounds.
      - Examples of polyatomic ions: Ammonium (NH4)+, Nitrite (NO2)- Nitrate (NO3)-.and many more. All the examples I mentioned are the usable forms for plants of nitrogen .
  - - - Plants carry out thousands of different chemical reactions similar to humans. Plants get all their essential elements from absorbing it from the soil. Usually taken up as positively charged cation or a negatively charged anion. The three key nutrients are nitrogen (N), phosphorus (P) and potassium (K). These elements make something called the Npk ratio. If the plant lacks one of these and it affects the plant's growth and this is called nutrient deficiency. #
- - - - Phase 1: Nitrogen comes from the atmosphere and the goes into the soil but is in an unusable form. Phase 2: Nitrogen-fixing bacteria in legume roots and in the soil convert the nitrogen gas (N,2) into ammonium (NH4)+. Phase 3: After Nitrifying bacteria turns ammonium (NH4)+ into nitrite (NO2)- which is nitrification. Phase 4: Then Nitrite (NO2)- turns into Nitrate (NO3)- by nitrifying bacteria. Phase 5: then assimaltion happens and transfers the usable nitrogen into the plants and herbivores eat the plants. Another thing that happens in phase 5 is that denitrifying bacteria breaks apart the Nitrate and releasing nitrogen back into the atmosphere as a gas. Phase 6: Animals poop out the nitrogen and decomposers turn them back into ammonium. #
  - - - Salmon carcass are left in the forest, Scavengers feed on the carcass. Either the Scavengers bring the carcasses into the forest or the scavengers poop the remains of the carcasses into the forest. After the marine derived nutrients enter the soil. Then nutrients taken up by vegetation through roots. Last herbivores feed on vegetation
- - - - Seed germination: zz
        
        What is a seed: An early embryonic plant covered in a seed coat. In order for the seed to grow it needs Moisture, warmth, nutrients, rich soil, sunlight and needs to be a good quality seed. Some important parts of the seed for growing are the root and sterms.
        
        What happens to a seed's plant cells as they grow: The plant cells inside, duplicate, Enzymes gets activated and the Embryo starts getting nourishment.
        
        definition for germination: The process of a seed turning into a plant.
    - - Examples of nutrients/Elements for plants and humans: Humans need: Carbon, Hydrogen, Nitrogen, Oxygen, Calcium, Phosphorus Plants need:
      - All organisms must take in matter from their environment to survive. Living things need only some of the elements to survive. For example, we as humans need about 20 different elements to live. Animals and Plants get different elements in order to produce DNA, proteins, and carbohydrates for animals or Chlorophyll in plants.
    - - How is nitrogen important: Its important because it gives organisms DNA, proteins and Chlorophyll in plants #
      - Where is Nitrogen stored: Its stored in the atmosphere, soil, living creatures and oceans and marine sadiment
