The death rate in the first year is very high at 90%, indicating a type III survivorship curve where most deaths occur early in life. The death rate in the second year is lower at 10%, indicating a type II survivorship curve where the death rate is relatively constant throughout life. The death rate in the third year is even lower at 5%, further supporting a type II survivorship curve. Thus, the survivorship of this population is best characterized as type III.
