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
We see an incredible amount of growth of the hyacinth in the control tank. For the experiment itself, two tanks of identical shape, color and size were taken. 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. One of the tanks was the control and the other one was the experimental tank. There was growth in the experimental tank also, but not as much because of the competition. We also predicted that the water clarity would decrease with an increase in plant life and the color of water would have a greenish tint to it. On the experimental tank, we followed the exact same steps but instead of putting one hyacinth, three were added. The main reason we chose to do this experiment was because of their fact that this type of occurrence can happen anywhere. The elodea that was put in the control tank also grew at an incredible rate, unlike the one in the experiment. The hyacint, our experimental variable, would grow nicely in the control tank, but it wouldn't grow as much in the experimental because of the presence of three other plants. The trait of the oxygen content was best reflected. 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 a better environment for other organisms, and supports bio-diversity. As we mentioned that the hyacinth would grow more in the control tank, it did.
