Watershed

The general observation is that the ground is sloped inwards from the road to the center of the grassy area. The water flow was anticipated to stay where it was because there was a small gradient therefore most of the water will need to be percolated downwards. There are human structures close as the black scribble areas is a road. Carbon enters the ecosystem from the atmosphere (such as in the form of CO2) as well as through decomposing matter. Nitrogen enters this area sometimes through fertilizers but I am sure that it has not been added in in a while and there are no areas that are higher then this so none would flow to it. Phosphorus enters the ecosystem when water enters through precipitation. They are not concentrated in any specific area that i can see because it is pretty much level maybe in the very small ditch the levels would be higher but the grass is the same color as other areas. The nutrients can leave this location becoming leached out or else they can be respired into the environment. They can become unavailable for use if they are leached out or if the soil is removed. The landscape affects the where the organism are located because it is very dry and pretty flat so most organisms are found in the tall weeds and trees. An organism might affect abiotic factors because it could change the pH of a soil if it removes some of the nutrients.
