Explain how much the post-hurricane birds varied from the original birds after 1 million years of natural selection. How do adaptations and natural selection explain the changes?

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process. 

Species, populations, community, ecosystem, biome, biosphere. 

I'm guessing that it's referencing the common folk or people of town or the people who are in the middle of the social and economical hierarchy
