Some abiotic factors that are plant needs to survive is sunlight, oxygen, and temperature.  I think the main abiotic factor is water though, because we are testing the plants with different types of water and their percentage of salt.  Some biotic factors that can affect our plant is bacteria and fungus.  Our seeds are competing with how much water they get because they only have limited water supply and they have to share it.  We can clearly see who won or who lost because if one seed is growing great and one is not growing good or is dead, then we can clearly see who won.  Our seeds can also fall under the category mutual-ism, because both organisms don't  loose anything when they are together.

       This week I noticed that the plants grew a little more.  The seeds with 0% salt are growing the most and are the biggest, and the seeds with 1% salt are in second place.  The seeds with 4% and 8% of salt are still very tiny and are not really growing.  During the nitrogen cycle, the bacteria turns into a gas, ammonia, that plants can use.  The ammonia turns into a nitrate ion and the plats take it in as protein.  Our plants are doing that because the ammonia is circling the plant right now.  The carbon cycle is the transformation of carbon back and fourth between living things and the environment.  Carbon is an element that can't be broken down, and our plants our giving out the carbon to the environment so we can breath.
