Populations and communities A : Vibrioberg and Vibrioville are 2 new cities that have developed near Baton Rouge. Both cities started with 10,000 people each. After one year, Vibrioberg had a growth rate of 6.2%, and the growth rate was coincidentally the same after year 2 as well. Vibrioville, on the other hand, had a ridiculously high growth rate of 12% after one year. Unfortunately, the growth rate proved to be too much, leading to water and air pollution problems and an infrastructure (streets, etc.) not prepared for such rapid growth. So, during year 2, Vibrioville’s growth rate dropped to only 0.4%. Therefore, after 2 years, Vibrioberg added ____(1)___ people, and Vibrioville added ___(2)____ people to their respective populations.
a. (1) 620 and (2) 1,200
b. (1) 1,240 and (2) 1,240
c. (1) 1,245 and (2) 1,278
d. (1) 1,278 and (2) 1,245
d. (1) 1,278 and (2) 1,245 Correct

d. the native species have not evolved and adapted to these organisms. Correct
Populations and communities B : In an ecosystem with many similar species, we typically find
