The fоllоwing аge pyrаmid shоws the proportion of femаle (red bars) at each age in a population of animals (males are represented by blue bars). Use this graph to answer the following question. Is this population likely growing, declining, or remaining stable? Why? (4.0 pts) Assume that the population above had either of the life tables listed below. Which life table would cause the population to grow faster during the next decade? Explain your reasoning (i.e., why is one table correct and why is the other table incorrect).
