6 Questions
What is the primary measure of species diversity in a community?
The number of species and their relative abundance
How do more diverse communities typically differ from less diverse communities?

What is the primary determinant of community structure according to the bottom-up model?
Nutrients and other abiotic factors
How do food chains and food webs differ in their structure?
Food chains are linear, while food webs are branching and more complex
