Elodea Canadensis, also referred to as American waterweed or common elodea, is an aquatic plant that is usually found in lakes, ponds or even rivers. Elodea helps support aquatic life such as young fish and amphibians by providing shelter and can be consumed as food by ducks and beavers. Elodea, like many other plants, relies upon photosynthesis to acquire its energy and to make food. To determine the importance of light energy in the process of photosynthesis, two Elodea plants were placed inside CO2 saturated water and exposed to different light intensities: one was under full light exposure while another was covered with mesh clothing to reduce the amount of light that it received; the solutions to this plants were then neutralized and compared to a control group which had no Elodea to see the amount of CO2 that each would have left after a period of an hour. The yielded results indicated that under high intensities of light, the Elodea plant photosynthesized and respired at the same rate; and while it was covered, it photosynthesized more because of an indicative decrease in CO2 levels. Therefore light energy is an essential aspect that affects the amount of CO2 that a plant can use in the process of photosynthesis.
