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.
