Comparing Biodiversity: Spiders, Spiders Everywhere!
1. First, make a hypothesis about the diversity of spiders in the (Habitats A & B). Without looking at the spider habitat sheet... which habitat do you think will be more diverse in terms of spider? Explain your reasoning.
I think habitat A will be more diverse in terms of spiders because it has more niches for different spiders to live in.

2. How many species of spiders did you find in…
Habitat A: 4
Habitat B: 2
3. What was the AVERAGE number of spiders you found per quadrat?
Habitat A: 5.6
Habitat B: 6
4. Twelve quadrats can fit in this area. How many spiders do you estimate are found in the whole area?
Habitat A: 22.4
Habitat B: 24
5. Look at the bottom sheet of paper with the spiders on it. How many spiders are there in…
Habitat A: 22
Habitat B: 20
6. Was your estimate close to the actual number of spiders in the area?
Yes, by 2-4 spiders close to the actual number of spiders
7. Why might there be a difference between your sample estimate and the actual number?
Because it's an estimate and an estimate is most likely not true, it's just a guess

8. Based on the proportions you just calculated (Table 4), do you think the species are evenly distributed within the habitats? No I don't think the species are evenly distributed within the habitats
Habitat A: .98
Habitat B: .90
9. Is this what you think it would be like in nature? Why?
Yes, in nature there really are a lot of species in different niches of the same ecosystem.
10. Was your original hypothesis supported by the data you collected today? Why or why not?
Yes, my original hypothesis was correct because I assumed that habitat A would have more diversity in terms of spiders
11. What did you learn about doing a biodiversity quadrat study?
Doing a biodiversity quadrat study I learned that it's a good way of finding out the population of the diversity of species by estimating.
