Members of an r-selected species characteristically

• grow slowly

• produce few offspring

• reach sexual maturity quickly

• have long life spans

Cycads (an ancient species of tree) 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

• K -strategists with a Type I survivorship curve.

• r -strategists with a Type III survivorship curve.

• K -strategists with a Type III survivorship curve.

• r -strategists with a Type II survivorship curve.

A species of dinosaur laid large numbers of eggs, and the hatchlings had high mortality early in life. But if they survived, the young dinosaurs were able to grow at a rapid pace and disperse into the environment in order to thrive. Which of the following best characterizes this species of dinosaur?

• The dinosaurs were r -strategists and exhibited a Type I survivorship curve.

• The dinosaurs were r -strategists and exhibited a Type III survivorship curve

• The dinosaurs were K -strategists and exhibited a Type II survivorship curve.

• The dinosaurs were K -strategists and exhibited a Type I survivorship curve.
