Cycads are gymnosperms that were diverse and abundant during the Mesozoic era. Extant species of cycads share many traits with those from the Mesozoic era. Cycads bear cones, are long-lived with slow growth rates, show late reproductive maturity, and have very few offspring. Based on this description, the cycads are: a. K -strategists with a Type I survivorship curve.
b. r -strategists with a Type III survivorship curve.
c. r -strategists with a Type II survivorship curve.
d. K -strategists with a Type III survivorship curve.
