What is the study of influence changes in a population's size?
The study of changes in a population's size is called demography. It involves analyzing birth rates, death rates, migration patterns, and other factors that can influence population growth or decline. Demographers use mathematical models to predict future population trends.
When population change over time has occurred?
Population change over time occurs due to a combination of factors such as births, deaths, migration, and natural disasters. These factors influence the growth or decline of a population, resulting in shifts in demographics and population size. Understanding patterns of population change is important for policymakers to plan for future resource allocation and infrastructure development.
Why is it false that food is the only limiting factor that keeps a population from growing too large?
While food availability plays a significant role in population growth, other factors such as disease, predation, competition for resources, and environmental changes also influence population size. A population can be limited by a combination of these factors, not just food availability.
The combined genetic information of all members of a particular population is the population's?
The combined genetic information of all members of a particular population is the population's gene pool. This gene pool contains all of the genetic variations that exist within the population, which can influence the population's ability to adapt to environmental changes and evolve over time.
What is the factor that controls the growth of a population?
the fitest survive
Demographers figure out population growth by comparing what?
the answer is by comparing birthrates and death rates
What do scientists use to predict population size?
There are several things that demographers use to predict how a population will grow. Some of them include gender balance, age, income levels and so much more.
How birthrates and death rates influence the size of a population?
Simple mathematics. If there are more births than deaths, the population will increase. If the reverse is true, the population decreases.
What is call when the birthrates are less than the death rates?
Population decreases
What are the major factors affecting population change?
Current birthrates and increased longevity.
What might be the consequences of falling birthrates in some European countries?
less population
Why do population are getting many?
Contraseptives and exponential birthrates can be two reasons for overpopulation
The astonishing growth in urban population between 1870 and 1900 was largely the product of?
rising birthrates
Refers to a shift in death rates followed by a shift in birthrates and its associated population boom?
The ice in the box
What is true of an industrial society?
birthrates drop, and may even drop low enough to reverse population growththere are fewer infant and child deathsThere are fewer infant and child deaths. Birthrates drop, and may even drop low enough to reverse population growth.
An isogen is a line connecting points of equal what?
birthrate
Where are the highest birthrates found in Latin America?
No. That would be Japan or Russia, where the population is actually decreasing.
