Lab 3 - Experiment 1: Interdependence of Species
Table 1: Interdependence of Species Results
Round
Species Missing (Bead Color and Name)
1
Yellow; Bees
2
White; Lichens
3
Blue; Humans
4
Red; Flowers
Hypothesis: If one species is taken out of the ecosystem, the remaining species will be affected negatively at some point in the process of their lifecycle in all scenarios except that in which the humans are removed.
Post-Lab Questions
1. Restate your hypothesis. Was it confirmed or denied? How do you know?
a. My hypothesis was confirmed by testing the effects of the ecosystem when a species was removed. In all of the scenarios, there was a species …show more content…
I found 5 species in both of my samples.
3. Which species is the most numerous in your sample area? Which is the least numerous?
a. The ryegrass was the most prevalent in both of the samples.
b. The least numerous was Zinnias in both of the samples.
4. If each peat 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?
a. I would believe that the ecosystem was in fact healthy because all of the species were prevalent.
5. How does biodiversity contribute to overall health of an ecosystem?
a. Biodiversity contributes to the health of an ecosystem because all of the plant life creates a balance within the ecosystem.
i. Additionally, in an unhealthy ecosystem a single species might completely overtake the rest of the species, causing the other species to disappear within the ecosystem.
