Yellow; Bees
2
White; Lichens
3
Blue; Humans
4
Red; Flowers
Hypothesis: If certain species are missing from the ecosystem except humans (blue), then all other species will feel the effects.
Post-Lab Questions
1. Restate your hypothesis. Was it confirmed or denied? How do you know?
If certain species are missing from the ecosystem except humans (blue), then all other species are negatively impacted. Confirmation of my hypothesis presented by testing the effects of the ecosystem …show more content…
How many different kinds of species did you find in your sample?
There were five different species in both samples.
3. Which species is the most numerous in your sample area? Which is the least numerous?
a. In both of the samples, Ryegrass was the most numerous.
b. In each of the samples, Zinnias was the least numerous.
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?
Yes, the ecosystem is healthy because of the diversity.
5. How does biodiversity contribute to overall health of an ecosystem?
Biodiversity contributes to the health of an ecosystem when various species depend, rely, and share the same responsibilities to ensure a healthy balance within the ecosystem. If one species, like the Ryegrass, over took the other species, there would be no diversity, and an unhealthy ecosystem.
