1: What is “r” stand for? growth rate
2: What happens if we have a positive “r”?
exponential growth and eventually hit logistic growth
3: What is “N”?
number of individuals in population
4: What is “K”?
the carrying capacity
5: Explain the survivorship curve. (Give an example for each)
TYPE I: Survival is likely early on
TYPE II: the organism dies at a linear rate.
TYPE III: Most of the organism dies early on
6: How does the environment affect the survivorship curve? the environment affect the survivorship curve by the stable environments promote a longer life expectancy
7: What are “r” selected species? Explain characteristics of these species.
Those that based their life on growth rate.
Characteristics of these species is Unstable environment, High rate of offsprings, Small body size, Early Maturity, Short Generation Time, Dispersed offspring.
8: What are “K” selected species? Explain characteristics of these species.
hose that are basing their lives on carrying capacity
Characteristics of these species is Stable environment, Large body size, Long life expectancy, High parental care, Fewer offspring.
