Sci 207 Wk 3 Lab
Lab 3 – BiodiversityDemonstration 1: Interdependence of SpeciesTable 1: Interdependence of Species ResultsRoundSpecies Missing (Bead Color and Name)1Trees: Orange2Flowers: Red3Humans: Blue4Bees: YellowPOST LAB QUESTIONSExplain how the ecosystem was affected by the missing species for each round of the demonstration.Round 1 =  Without trees, pollution would destroy our environment and air. They wouldn’t be recycled and we could possibly die.Round 2 =  If flowers were missing the bees wouldn’t hae their food source. Without their food source, pollination wouldn’t happen and life can cease to exist for the trees, which recycles our air.Round 3 = without humans the ecosystem would probably be better off. Having us humans in the ecosystem, throws it out of wack. We need to minimize our footprint to avoid damage.Round 4 = The decline of bees can damage the ecosystem. Without them the treeas wouldn’t be pollinated as neither will the flowers which in turn provide recycled air that we need to breathe.Provide one action we as humans engage in that leads to the extinction of each of these components.Action affecting Lichens = Lichens depend on trees so they can grow. Humans cutting down these trees can affect their cycle and can cause pollution.Action affecting Trees =  We destroy trees by our fuel. Our fuel affects trees when it releases it carbon dioxide into the atmosphere.
Action affecting Flowers =  Our pollution affects the flowers the same way that it would affect the trees. It would kill of the natural life order.Action affecting Bees = Humans sing pesticides cause bees to be killed off and it affects the cycle.Provide three specific actions that humans can take to minimize our impact on the ecosystem and ensure the survival of lichens, trees, flowers, and bees.Action 1 = Take care of toxic waste safely, and go green.Action 2 = Plant more trees, and spread more seeds to compensate for those that have been chopped down.Action 3 = Reduce our carbon footprintExperiment 1: Diversity of PlantsTable 2: Number of Each Plant Species Present in Pot 1 and Pot 2Species ObservedNumber in Pot 1(sunlight)Number in Pot 2(shade)Zinnia30Marigold25Morning Glory 42Cosmos721Ryegrass223Total Number of Species in Pot:1951I didn’t have many in my pot that were full grown since I only started this experiment last Tuesday.POST LAB QUESTIONSDevelop a hypothesis on which pot you believe will contain the highest biodiversity.Hypothesis = I believe the pot that is in the direct portion of the sunlight will achieve the highest biodiversityBased on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1?  Explain how you determined this.Accept/Reject = I would have to reject my hypothesis. Even though I have been watching this experiment for the past 6 days it seems that the pot in the shade grew faster than the pot in the sun.If each pot was a sample you found in a group of wildflowers, would you determine based on the diversity of flowers that the ecosystem is healthy?  Why or why not.Answer = I would determine that the ecosystem was healthy and I would also look at the brightness of the greenery.
