Here's why:
* Type I curves are characterized by high survival rates early in life, with mortality increasing sharply in later life. This is typical of species that invest heavily in parental care and have a relatively low number of offspring.
* Giraffes fit this pattern:
* They have a long gestation period, giving birth to a single calf at a time.
* The calf is heavily reliant on its mother for protection and nourishment for the first few years of life.
* Giraffes are also relatively long-lived animals.
Therefore, a giraffe's survivorship curve resembles a Type I curve due to their high early survival rates and increased mortality in old age.
