Hypothesis: If trees were not part of the ecosystem, then there would be a lack of food for the bees.
Post-Lab Questions
1. Restate your hypothesis. Was it confirmed or denied? How do you know?
If trees were not part of the ecosystem, then there would be a lack of food for bees. It was confirmed because of the chart that showed each part of the ecosystem and how it affected other parts of the ecosystem.
1. Indicate which species was removed during each round of the experiment.
Flowers were removed the first round, bees in the second round, trees in the third round, and humans in the last round.
1. Explain how the ecosystem was affected by the missing species for each round of the experiment.
In the first round the flowers weren’t there, which means the bees would lose out on a food source. In the second round there were no bees, which means the flowers and trees would not get pollinated. In the third round there were no trees, which means that the flowers wouldn’t get shade and wind protection. In the last round there were no humans, which I personally felt made the least significant change to the ecosystem.
1. What actions do we as humans engage in that can lead to extinction of any of these components?
We as humans pollute the air and environment with our cars and littering carelessly. Also, we chop down trees to build building we do not need as much as the trees.
1. What can we do to minimize our impact on the ecosystem?
We can plant more trees and flowers, use environmentally safe cars, pick up trash or throw our...
