1: What is “r” stand for?
Growth rate
2: What happens if we have a positive “r”?
There will be exponential growth and eventually logistic growth
3: What is “N”?
Number of individuals in a population
4: What is “K”?
carrying capacity
5: Explain the survivorship curve. (Give an example for each)
TYPE I: Survival early on an example are humans
TYPE II: Dying in a linear way an example is a robin
TYPE III: Organism dies early an example is a frog
6: How does the environment affect the survivorship curve?
A stable environment makes surviving easier
7: What are “r” selected species? Explain characteristics of these species.
Unstable environment
High rate of offspring
Small body size
Early Maturity
Short generation time
Dispersed offspring
8: What are “K” selected species? Explain characteristics of these species.
Stable environment
Large body size
Long life expectancy
High parental care
Fewer offspring
