IBDP Biology Question Analysis Topic: Biology - Population
Exam Questions:
1) When does the population in a metro city tend to increase?
2) When does the population in metro city tend to decline?
Answer:
For IBDP Biology, you should know:
1) When the natality rate (the number of births) and immigration rate (the number of people of the same species that have moved into the habitat from elsewhere) rise, the population of a metropolis tends to grow.
2) If the natality rate (the number of births), immigration rate (the number of individuals of the same species who have entered the habitat from elsewhere), mortality rate (the number of deaths), and emigration rate (the number of individuals of the population who left the habitat and went elsewhere) all decrease, the population in a metropolis tends to decrease.
Work hard for your IBDP Biology examination!
End of analysis. Great!
