Three species' survivorship curves are plotted on a semi-log scale: humans (Type I), squirrels (Type II), and oysters (Type III).
Which life-history strategy matches species III?
- Acheck_circle
Many offspring with little parental care; high early mortality.
- B
Few offspring with high investment; low juvenile mortality.
- C
Constant per-capita death rate at all ages.
- D
Mortality rate is highest in old age.
Explanation
Type III curves show steep early mortality with relatively constant survival in adults, typical of r-selected species (oysters, fish, many invertebrates).
