Type I survivorship curve is characterized by high survival rates during early and middle life, followed by a rapid decline in survival in later life. Humans and large mammals such as elephants and whales exhibit this type of survivorship curve

Type 1 Survivorship Curve

Type II survivorship curve is characterized by a relatively constant decline in survival rates over an organism's lifespan. This type of survivorship curve is commonly observed in birds and small mammals.

Type 2 Survivorship Curve

Type III survivorship curve is characterized by low survival rates early in life, with the majority of mortality occurring during the juvenile stage. This type of survivorship curve is common in species that produce a large number of offspring, such as fish and insects.

Type 3 Survivorship Curve

Survivorship curves can provide important information about the life history of a population, including its reproductive strategy and potential for growth.

Comparison:

Survivorship curves are graphs that show the proportion of a population surviving at different ages. Understanding these curves can provide insight into population dynamics, life histories, and ecology.

Summary:

The study of survivorship curves is an important area of research in population biology and has practical applications in areas such as conservation biology and public health.
