Aquatic Ecology essays

Aquatic Ecology essays 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 plants. 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. The hyacint, our experimental variable, would grow nicely in the control tank, but it wouldnt grow as much in the experimental because of the presence of three other plants. We also believed that the number of organisms or protists would decrease in the experimental because of the sudden change in their environment. 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...
