Population Environmental Science

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

Population growth rate is figured out by

• Births-deaths

• Birth + deaths

This graph represents the _______ growth curve.

• Exponential

• Logistic

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

• Carrying capacity

• substantiated curve

• dependent factors
