Pond Lab Report

Introduction In the pond water lab experiment, our group has chosen to test the effects of nitrates on a pond community. After a lot of research, we have found that nitrates in a pond community can increase growth rates of plants and some animals. The effects of nitrates include algal blooms, which is when too much food or nutrients are consumed by producers, (i.e. algae) causing them to grow and spread, so they consume …

…I think day 4 might have been lower than the actual population drop that was happening. Besides that, with a little bit of nitrates added, the population shrinkage was slow. In container 3, this seemed to be the healthiest community. I think on day 8 the nitrates ran out, causing populations to drop quicker. In container 4, we saw a lot of plant life, but a lot of the animal life seemed to die, which the graph shows well.
