I was able to conclude from this experiment that all living things need a balanced environment in order to survive.
As I predicted in my hypothesis, jars 3 and 4 had the best survival because plants and animals need each other in order to survive.
In these jars the snails needed the plants as a food source. The snails also need the plants to take in CO2 to produce O2.
The plants in these jars needed the snails as a source of Co2 for their survival. In these jars both snails and plants survived because they depended on each other.
There were some changes in the clarity of water,the PH levels, and the O2 levels. This was due imbalance of the snails and plants.
When there are too many plants and no snails there is not enough CO2 to support the plants. When ther are too many snails and not enough plant, the snails use up the O2 faster than plants can produce it.
Because of these findings I can conclude that not only due plants and animals need each other for survival but the balance between the two is much more important for the long term survival of each.
