Exponential Model
populations of bacteria
What does a positive growth rate indicate
population is increasing
Exponential Model of Population Growth
a pattern of population growth which organism reproduce continuously at a constant rate
Is the maximum per capita rate for humans high or low compared to other species
low
What is the population growth rate formula
(births + immigration)-(deaths + emigration) x100 Initial population
Doubling times
is the amount of time that is required for the population to double in size
what does dN symbolize dt
the change in population size over time
What is population growth rate
the fractional rate at which the number of individuals in a population increases or decreases
Per capita growth rate (r)
the difference between the per capita brith rate and the per capita death rate of a population
In a population of 100 snakes, if 25 was born in one month, what would be the per capita birth rate
0.25
What shape is made when exponential growth is plotted on a graph
J- shaped
Zero population growth (ZPG)
a situation in which the death rate and the birth rate are in equilibrium
