This investigation compared the water qualities of Cherry Creek and Bear Creek in order to determine how the physical, chemical, and biological factors of the streams impacted the amount of life present within them. This investigation attempts to answer the question, “How are abiotic elements related to the number and abundance of macroinvertebrates found in the two streams?”
Water quality is the term used to indicate a body of water’s suitability for use (Ayers 1976). Water quality can be assessed based on its physical, chemical, and biological characteristics that it portrays (Metcalfe 1989). All of these elements interact together to create the ecosystem in which an organism lives in. The investigation looked at the physical parameters, temperature and water quality of the streams, and the bioindicators present within the streams.
The physical parameters consisted of observations regarding the physicality of the streams. That is, how wide and deep the water was, and how fast was the flow rate of the water. These elements are important because they affect what kinds of organisms can survive in different parts of the water. Some organisms may not be able to survive in deeper waters, whereas others may not be able to survive if …show more content…

The independent variable, water quality, will be determined through the measurements of pH, temperature (measured in degrees Celsius), phosphate, nitrate, ammonia, dissolved oxygen and dissolved solute levels (all measured in parts per million) in the water. The dependent variable will consists of the number and abundance of different types of organisms and plants present in the streams.
If the number and abundance of macroinvertebrates is dependent on the quality of water in the streams, then Bear Creek will have a greater abundance of macroinvertebrates due to its better quality of
