What are age structure diagrams?
Age structure diagrams (also known as age pyramids) are graphical representations that show the distribution of different age groups within a population.
What does biotic potential refer to?
Biotic potential refers to the maximum rate at which a population can grow under ideal conditions with unlimited resources.
What is carrying capacity?
Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support without degrading the ecosystem or depleting resources.
What is demographic transition?
The demographic transition refers to the process of a population transitioning from high birth and death rates to low birth and death rates as a result of social and economic development.
What are density dependent factors?
Density dependent factors are environmental factors that affect a population’s size and growth rate based on the population’s density.
What are density independent factors?
Density independent factors are environmental factors that affect a population’s size and growth rate regardless of its density.
What is exponential growth?
Exponential growth refers to a rapid and continuous increase in population size over time, where the growth rate is proportional to the current population.
What are generalist species?
Generalist species are organisms that can adapt and thrive in a wide range of environmental conditions and can consume various types of food.
What are K-selected species?
K-selected species are organisms that have low reproductive rates, produce fewer offspring, and have longer lifespans.
What is logistic growth?
Logistic growth refers to a pattern of population growth where the initial exponential increase slows down and eventually levels off due to environmental resistance factors.
What is population density?
Population density is a measure of the number of individuals living in a particular area, usually expressed as the number of people per square kilometer or square mile.
What are r-selected species?
r-selected species are organisms that have a high reproductive rate and produce many offspring, but provide little parental care.
What is replacement level fertility?
Replacement level fertility is the total fertility rate needed for a population to replace itself without any increase or decrease.
What is the Rule of 70?
The Rule of 70 is a mathematical formula used to estimate the doubling time of a growing quantity based on its annual growth rate.
What are specialist species?
Specialist species are organisms that have specific requirements and can only survive in a narrow range of environmental conditions.
What are survivorship curves?
Survivorship curves represent the pattern of survival for individuals in a population over their lifespan.
What is total fertility rate?
The total fertility rate refers to the average number of children that would be born to a woman over her lifetime, given the current birth rates.
