and how they change over space and time.
What is population density? Be able to give an example. - ANSWER Population density is the number of
organisms in a given unit area
Be able to identify the 3 different survivorship curves by sight. Also, be able to explain and give an
example organism that exhibits each type of curve. - ANSWER Type I - most individuals survive to older
age
Type II - Survivorship constant over life span
Type III - Lone survivorship at early age
What are some of the key life history traits of a population? What are the two main strategies in life
history traits? Which survivorship curve type does each of these two strategies usually exhibit? -
