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

k-strategist with a type 1 survivorship curve.

Explanation:

The species can show two type of strategy known as r - strategy and k strategy depending upon the type of their reproduction, offspring production and social interaction. The survivorship curves explain the survivor percentage of the organism.

The cycads are k strategist species because they have low offspring and protects their seeds from the external environment. They show type I survivorship curve because they have slow growth and live long in their life and shows death at the later stages of life.

Thus, the answer is k-strategist with a type 1 survivorship curve.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
