Question

students visit two parks and wonder which park has the most biodiversity. the students work with their local parks department to study the species richness, species evenness, and biodiversity of trees in the two parks. species evenness is a measure of how evenly species are distributed within an area. figure 1 shows the data the students obtained. figure 1: forest data park 1 park 2 images of trees species percentages: park 1: yellow : 25%, green pine : 25%, green broad : 25%, green narrow : 25%; park 2: yellow : 6%, green pine : 12%, green broad : 70%, green narrow : 12% describe the biodiversity of the parks in terms of their species richness and species evenness. choose... less than greater than the same as of park 1 is the same as that of park 2. the species evenness of park 1 is choose... that of park 2. the park with more biodiversity is choose.... more biodiversity leads to choose... ecosystem stability.

Explanation:

Step 1: Analyze Species Richness

Species richness is the number of different species. Both parks have 4 tree species (yellow, green, pine - like, and the slender - shaped), so species richness of Park 1 is the same as that of Park 2.

Step 2: Analyze Species Evenness

Species evenness is the distribution of species. Park 1 has each species at 25%, while Park 2 has uneven distributions (6%, 12%, 70%, 12%). So Park 1’s evenness is greater than Park 2’s.

Step 3: Determine Biodiversity

Biodiversity depends on richness and evenness. Since richness is same and Park 1 has better evenness, Park 1 has more biodiversity.

Step 4: Biodiversity and Ecosystem Stability

More biodiversity leads to greater ecosystem stability (as diverse ecosystems are more resilient).

Answer:

s (for each drop - down):

1. Species richness of Park 1: the same as
2. Species evenness of Park 1: greater than
3. Park with more biodiversity: Park 1
4. More biodiversity leads to: greater
