Population and Survivorship Curves

A mouse with a short life span, produces more offspring than can survive, and gives little or no parental care is a

• R-selected species

• K-selected species

An elephant that has only 1 offspring at a time, has a long life span, and provides parental care throughout maturity is a

• K- selected species

• R-selected species

A pattern of survival over time in which there is high survival throughout most of the life span, but then individuals start to die in large numbers as they approach old age.

• Type i survivorship

• Type ii survivorship

• Type iii survivorship

A pattern of survival over time in which there is a relatively constant decline in survivorship throughout most of the life span.

• Type ii survivorship

• Type i survivorship

• Type iii survivorship

A pattern of survival over time in which there is low survivorship early in life with few individuals reaching adulthood.

• Type III survivorship

• Type II survivorship

• Type I survivorship

When the exponential growth hits the ecosystems _________ it levels off and changes to logistic growth.

• Carrying capacity

• dependent factors

Which would have the lowest survival rate in the beginning, but if it survives to maturity, it can live a long time.
