Bottle Habitat

For our Ecology segment we had to make a bottle habitat that included plastic bottles to hold pond water, dirt and rocks, and insects (optional). We had to use rope to allow water to get from one bottle to another (if we had multiple bottles), and sponge in any of the bottle openings. My groups bottle habitat was made out of a large cheese ball container, and two 2liter bottles. The cheese ball container is on one end with one 2liter cut into its side. The 2liter that comes our from the container is like a bridge that connects the container to the second 2liter. In the cheese ball barrel we put pond water and let one end of the rope rest just below the water line. If we follow the rope, we will enter into the "bridge" of our habitat which holds some dirt and plants that we took from bottle habitats of previous classes. From there the rope continues into the second 2liter which holds the same content as the "bridge". After weeks of letting the habitat grow and change we noticed a growth in the plants, and we also acquired a snail! I'm not sure how it got there but now it is there and living in the habitat. Our bottle habitat shows the natural process of plant growth and how an ecosystem can survive with the bare minimum. With water, a medium for organisms to grow in, and light, you get a sustainable environment.
