Aquatic Ecology
Plants are the most important part of our ecology, both in water and land. Therefore, for our experimental variable, we chose to increase the amount of plant life in an aquztic environment. Plant life is really important in natural world mainly because it is a provider of oxygen for other organisms. So, by increasing the number of plants, we planned to observe the effect it had on the other organisms. Our hypothesis states: the more the plant life in the tank, the less bio-diversity within the tank. The main reason behind this thought were, plants will block sunlight from being passed through into the tank and more plant means more competition for nutrients which eventually will make weaker organisms die out. Some chemical parameters that we tested were (1)dissolved oxygen, and (2) water clarity and the color of water. Some biological parameters that we tested for were (3) the length of the plants, (4) the weight of the plants, and (5) the number of protists. We believe that there would be a higher oxygen content initially because of increased number of plants, who survive through the process of photosynthesis. However, this will step down because of the lack in the circulation of water due to the overpopulation of pl
The main reason we chose to do this experiment was because of their fact that this type of occurrence can happen anywhere. The reason we chose to test those particular parameters was that an increase in plant life would most certainly result in an increase in the oxygen content. Testing the water clarity was chosen because an increase in the plant life would block a majority of sunlight or kill organisms, producing decaying matter that will most likely change the clarity and the color of water. Measurement of the plant itself would give us an idea of what is happening to the plant itself. The presence of the number of protist will reflect the effect on their organisms. The predictions that were made based on the hypothesis is not as much reflected in the results as hoped. The trait of the oxygen content was best reflected. As we mentioned that the hyacinth would grow more in the control tank, it did. Unlike what we had predicted, the water clarity of our experiment actually increased, and other organisms, namely protist surprisingly survived better than those in the control. The clam that was put in the control tank died, unlike the one in the experiment, which together with the number of protists gives us an idea that more plants actually creates
