In one to three paragraphs, list and discuss all the abiotic factors you noted in your study. Include but do not limit yourself to temperature, precipitation, soils, and water flow. Be clear, thorough, and scientifically accurate. Include maps that show abiotic conditions, such as local soils, if possible.

I chose Feather River for my Eco-system in Oroville California. The limiting factors in my Eco-system are the current, sunlight, temperature of the water and the water level. Feather River has a strong current that limits the types of fish that are in the water. The temperature is a major factor because the direct runoff from the melting snow causes the water to be very cold which also effects the depth and width of the river. There is no shade so sunlight shines down which allows algae to flourish. This ecosystem is an open system because there is a steady flow of water going through. Defining the limiting factors of an ecosystem are important because it affects what type of species or how a species survives in the ecosystem. The cold water effects the diversity of fish in the waters. The current effects what type are fish travel through the water. Only fish with streamlined bodies can travel efficiently through the water and they tend to go against the current. The rivers water level is low in the beginning of summer but soon rises when the temperature rises. The temperature of the river does not change, it only gets warmer further down stream.
