What is the definition of a population?
What is the definition of a population?
A group of individuals of the same species living in the same area
What are the factors that control population size?
What are the factors that control population size?
Birth rate, death rate, immigration, emigration
What happens when the birth rate is equal to death rate?
What happens when the birth rate is equal to death rate?
The population won't increase.
List three characteristics of a population.
List three characteristics of a population.
geographic distribution, density, growth rate.
What is population density?
What is population density?
Number of individuals in a certain area
A population that is increasing in size is shaped like a .....
A population that is increasing in size is shaped like a .....
triangle
A population that is smaller at the bottom than the top is....
A population that is smaller at the bottom than the top is....
decreasing in size
What factors increase the likelihood of a stable population?
What factors increase the likelihood of a stable population?
death rate is equal to birth rate; good healthcare, job opportunities, stable economy, plentiful food supply
How could a country with a increasing population change their population to a stable population size?
How could a country with a increasing population change their population to a stable population size?
Increase opportunities for education, stabilize food supply, improve healthcare
What technological advancements have contributed to long life expectancies?
What technological advancements have contributed to long life expectancies?
Vaccines, antibioitics, improved sanitation, improved surgical procedures
What is a prey?
What is a prey?
An organism that eat is eaten by another organism; could be a plant or animal
What is a niche?
What is a niche?
The role an organism has in its habitat.
What is the relationship between a niche and competition?
What is the relationship between a niche and competition?
No two species can survive in the same niche at the same time in the same place
How does competition control population size?
How does competition control population size?
In competition, only one species survives; the other species must emigrate or die, decreasing the population size
What is a parasite?
What is a parasite?
A parasite is an organism that benefits from a symbiotic relationship while the other organism is injured by the association.
List the factors that limit population size.
List the factors that limit population size.
Predation, Competition, Parasites, Disease
Explain how limiting factors affect population size.
Explain how limiting factors affect population size.
LImiting factors prevent populations from growing because the prevent individuals from moving in and reproducing successfully
What does density independence mean?
What does density independence mean?
Density independence is when a limiting factor affects a population regardless of population density.
What does density dependence mean?
What does density dependence mean?
Density dependence depends on the number of indviduals present in a population; as population increases in density, effects are greater
Two species of bacteria are grown together in a petri dish. One reproduces more than the other. What factor is likely limiting growth, and is it density independent or density dependent?
Two species of bacteria are grown together in a petri dish. One reproduces more than the other. What factor is likely limiting growth, and is it density independent or density dependent?
Competition is density dependent.
Name the two types of growth curves.
Name the two types of growth curves.
Logisitic and Exponential growth curves.
What is carrying capacity and in which type of growth curve is it seen in?
What is carrying capacity and in which type of growth curve is it seen in?
Carrying capacity is the number of individuals a population can sustainably support in an environment. Logisitic.
What happens to a population that exceeds carrying capacity?
What happens to a population that exceeds carrying capacity?
The population decreases due to starvation, disease, or some other density dependent factor
Why does a population experience exponential growth?
Why does a population experience exponential growth?
Populations can experience exponential growth because it is not limited by any factors.
Why is the human population currently experiencing exponential growth?
Why is the human population currently experiencing exponential growth?
The human population is experiencing exponential growth as humans have technological advancements that have allowed them to exceed their natural carrying capacity.
