- Figure 45.16 Age structure diagrams for rapidly growing, slow growing, and stable populations are shown in stages 1 through 3. What type of population change do you think stage 4 represents?Populous nations such as China have instituted strict policies tocurb population growth. In 1979, China implemented a “one-child”policy.Do you think that such strict control methods are appropriatefor population control?In many rural areas, stray cats are a problem as they may return to being wild feral cats that have not been spayed or neutered can reproduce, which may result in a population of feral cats. One pair of cats can produce 12 kittens in one year, and half of these kittens are female; this increased population would potentially produce 84 kittens in the second year. In 5-years, the population could reach almost 33000 feral cats. A) What conditions or factors would have to be in place for the population to achieve its biotic potential?

Over the years, the winter coloration (the color of the rabbit's fur) of the surviving rabbit population changed. The graph shows the change in winter coloration of rabbits between 185 to 2000. Based on the data, we could hypothesize that A) the winters are longer in length. B) the snowshoe rabbit has migrated to another area. the amount of snow cover varied over the years. D) more snowshoe rabbit predators have moved into Manitoba. % Population
