1: What is “r”
stand for?
R stands for growth rate
2: What happens if we have a
positive “r”?
You'll have exponential growth and with some limiting factor you're going to have logistic growth.
3: What is “N”?
N is the number of the population
4: What is “K”?
K is the carrying capacity
5: Explain the survivorship curve. (Give
an example for each)
TYPE I: Most individuals live to adulthood
TYPE II: a linear line where individual's chance of dying is independent of its age.
TYPE III: few individuals live to adulthood.
6: How does the environment affect the survivorship
curve?
environment stability differs the survivorship curve.
7: What are “r”
selected species? Explain characteristics of these
species.
Species that base their life on growth(quickly grow)
unstable environment, high fecundity, small body size, early maturity, short generation time, dispersed offspring.
8: What are “K”
selected species? Explain characteristics of these
species.
Base their life on carrying capacity.(logistic growth)
Stable environment, large body size, long life, high parental care, fewer offspring
