Introduction: Every creature that is living is part of an ecosystem; Nonetheless there are fundamental features to these ecosystems which are a principle for basic life. We must look at the importance to understand the course biotic and abiotic factors interact as well to help us understand the way organisms are able to develop, sustain and thrive all on to itself. Water is a key factor and is absolutely the most necessary substances needed. With only about 2 and a half percent of the worlds water is only fresh water. With only less than 1/10000th of the worlds water supply is available for biotic components of ecosystems. Seeing how little water we have in the world but seeing our population increase makes all this astonishing. Methods: Before beginning the experiment, I was required to gather all the materials. I began the experiment when all the materials were gathered. The first step was to fill four cups with 600 ML of water. I used a measuring cup to ensure accuracy. I then used red dye and blue dye to stain the water. Two cups received blue dye and the last two cups I used red dye. Once I mixed the dye, I separated two cups to create two groups each group containing (1) Red dyed water and (1) blue dyed water. For group A I added 4 spoonsful of salt to both cups. For group B I didn’t add anything else. Taking two almost identical stalks of celery I sliced them down the middle almost creating “legs”. I then placed each leg in one of the cup groups, straddling the cups. After 6 hours had passed, I examined the stalks of celery. In order for me to do this I looked to see where the dye stops and began to make cross-sectional cuts until I saw the presence of the dye. I measured the distance of the traveled dye helped me compare the effect of the salted water on the celery stalks. Once the Distances were measured, I started to pull apart the stalks to observe the dye within them. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - of the lab I observed the stalks of celery which was grown and matured, it was introduced into salt water the celery quickly withers and started to dry out.
