Plant and Animal Interrelationships Purpose- to determine the difference in carbon dioxide taken in between a snail (animal) and a elodea (plant) also to see if a symbiotic relationship is present between these two organisms if so does it relate to photosynthesis in any way.Hypothesis- If a photosynthetic organisms is placed in a lighted area and anther in a dark area then the one in the lighted area is going to take in more Carbon dioxide then the one in the dark area.Materials- the Materials that are needed for this project are as follows. glass test tubes, rubber stoppers, Brothymo to measure the amount of Carbon dioxide present in the test tube blue equates to oxygen yellow is carbon dioxide, snails, Elodea, a lamp preferably florescent or one that mimics the sun, test tube racks, eye dropper, distilled water, scotch tape, sharpie marker, and a dark cabinet. Procedure- before you begin the experiment take some time to discus the relationship between li
after an initial discussion proceed to locate the 8 test tubes label them A1, A2, B1, B2, C1, C2, D1, and D2 also fill them most of the way full with distilled water but leave enough room for there to be an air pocket as well as room for the stopper. little blue some oxygen, snail aliveB2. these are the two controls in the experiment. yellow allot of carbon dioxide B1. blue water oxygen produced snail dead C1 little blue some traces of oxygenC2 yellow Carbon dioxide is present D1. no blue no yellow snail aliveResults after 48 hrs. very little blue some oxygen, snail deadB2. then add 4 drops of Brothymo to each one of the tubes. take the test tube rack labeled light underneath the lamp and the rack labeled dark in the dark cupboard. then take the test tubes labeled C1 and C2 and place a Elodea plant in each one, put the stopper on both and then proceed to place C1 in the light rack and C2 in the dark rack. then take the two test tubes labeled B1 and B2 and put a snail in each one of the put a stopper on each and place the B1 in the light rack and B2 in the dark one.
