If the birth rate is higher and the death rate is lower what is the population growth rate?
The population growth rate will be higher
Does emigration lower or higher the growth rate?
Lower
What is exponential growth?
Growth without limiting factors
What is logistic growth?
Growth with limiting factors and a carrying capacity
Where is population growth the highest in logistic growth?
At the carrying capacity
Where is population growth the highest in exponential growth?
It does not have a maximum
What does N stand for?
Population size
What does No stand for?
Initial population size
What does r stand for?
Population growth rate per capita
dN/dt
Population growth rate
Density-dependent limiting factors examples
Shelter and food
Density-independent limiting factors examples
Disease, predators, parasites
What happens to exponential growth rates when r goes up?
The slope increases
What happens to logistic growth rates when the K is lower?
It reaches it’s peak quicker.
