Consider a perennial plant with four life stages: seed, seedling, small adult, and large adult. Seeds survive to seedlings with a probability of 50 percent; seedlings survive to be small adults with a probability of 20 percent; small adults survive to be large adults with a probability of 20 percent. Both small adults and large adults produce an average of 10 seeds. Use this information to fill in the life table that follows; then calculate the R0 and explain whether the population is increasing, stable, or decreasing.

$\begin{array} { | l | l | l | l | } \hline \text { Age Class } ( x ) & \text { Survival Rate } \left( \mathrm { s } _ { \mathrm { x } } \right) & \text { Survivorship } \left( \mathrm { l } _ { \mathrm { x } } \right) & \text { Fecundity } \left( \mathrm { b } _ { \mathrm { x } } \right) \\\hline \text { Seed } & & & \\\hline \text { Seedling } & & & \\\hline \text { Small adult } & & & \\\hline \text { Large adult } & & & \\\hline\end{array}$

The Answer of Consider a perennial plant with four life stages: seed, seedling, small adult, and large adult. Seeds survive to seedlings with a probability of 50 percent; seedlings survive to be small adults with a probability of 20 percent; small adults survive to be large adults with a probability of 20 percent. Both small adults and large adults produce an average of 10 seeds. Use this information to fill in the life table that follows; then calculate the R0 and explain whether the population is increasing, stable, or decreasing. $$\begin{array} { | l | l | l | l | } \hline \text { Age Class } ( x ) & \text { Survival Rate } \left( \mathrm { s } _ { \mathrm { x } } \right) & \text { Survivorship } \left( \mathrm { l } _ { \mathrm { x } } \right) & \text { Fecundity } \left( \mathrm { b } _ { \mathrm { x } } \right) \ \hline \text { Seed } & & & \ \hline \text { Seedling } & & & \ \hline \text { Small adult } & & & \ \hline \text { Large adult } & & & \ \hline \end{array}$$ R₀: _____________________
