Explanation / Answer

Age (in yrs)

Number alive

Survival rate

Survivorship = SURVIVAL RATE/ MAXIMUM SURVIVAL RATE

Fecundity

1000

(900/1000) = 0.9

0.9/0.9 = 1

900

(800/900) = 0.89

0.89/0.9 = 0.989

800

(700/800) = 0.87

0.87/0.9 = 0.967

700

(600/700) = 0.85

0.85/0.9 = 0.944

600

(500/600) = 0.83

0.83/0.9 = 0.922

6.5

500

(400/500) = 0.8

0.8/0.9 = 0.889

4.2

400

0.25

0.25/0.9 = 0.278

1.2

VAL/400 = 0.25

SO, VAL = 100

0/100 = 0

0/0.9 = 0

0.2
