Vaccines, antibioitics, improved sanitation, improved surgical procedures
The population won't increase.
Logisitic and Exponential growth curves.
The human population is experiencing exponential growth as humans have technological advancements that have allowed them to exceed their natural carrying capacity.
An organism that eat is eaten by another organism; could be a plant or animal
geographic distribution, density, growth rate.
Birth rate, death rate, immigration, emigration
Competition is density dependent.
No two species can survive in the same niche at the same time in the same place
triangle
In competition, only one species survives; the other species must emigrate or die, decreasing the population size
Density dependence depends on the number of indviduals present in a population; as population increases in density, effects are greater
The population decreases due to starvation, disease, or some other density dependent factor
Populations can experience exponential growth because it is not limited by any factors.
Predation, Competition, Parasites, Disease
Density independence is when a limiting factor affects a population regardless of population density.
death rate is equal to birth rate; good healthcare, job opportunities, stable economy, plentiful food supply
The role an organism has in its habitat.
Number of individuals in a certain area
Increase opportunities for education, stabilize food supply, improve healthcare
A group of individuals of the same species living in the same area
LImiting factors prevent populations from growing because the prevent individuals from moving in and reproducing successfully
A parasite is an organism that benefits from a symbiotic relationship while the other organism is injured by the association.
decreasing in size
Carrying capacity is the number of individuals a population can sustainably support in an environment. Logisitic.
