Match each term with its definition. a. carrying capacity sudden extreme decrease in population b. exponential growth the maximum population of a species that the resources of its habitat can support c. logistic growth s-curve (population increase that is slow, then accelerating, then slowing and finally leveling off) d. population crash population increase where the rate of growth stays the same but numbers increase at an accelerating rate

Apopulation of ten mating pairs of butterflies colonize a new area with no predators and a number of flower species large enough to support a butterfly population of 2000 individuals. each pair can have 20 offspring per year. for the first 2 years in the new area, the growth curve for this butterfly population will show: exponential growth because the colonizing population size will remain below the carrying capacity for the first two years. logistic growth because they will reach maximum population size immediately after colonization. exponential growth because only a few individuals will have offspring. logistic growth because the colonizing population will reach carrying capacity within the first two years.

Imagine you are standing in a field and you see a group of butterflies. you notice that the butterflies are not identical to each other even though they are all from the same species and the same population. one day you notice an individual that looks noticeably different from the other butterflies in the population. it has much larger wings and can fly faster than the other butterflies. this difference allows the butterfly to escape predation more efficiently than other butterflies in the population. the difference came about because this butterfly spent more time developing in warm moist areas of the habitat than other butterflies. do you expect the following generations to be composed of butterflies with larger wings? a) yes, this trait is advantageous so more butterflies will choose to develop in warm moist areas of the habitat. b) yes, this represents a genetic mutation that will be passed onto offspring. c) no, this represents non-heritable variation caused by the environment. d) no, this represents heritable variation but this trait does not increase ability to mate so will not be passed to the next generation.

Apopulation of glasswing butterflies exhibits logistic growth. the carrying capacity of the population is 200 butterflies, and rmax, the maximum per capita growth rate, of the population is 0.10 butterflies/(butterflies •month). calculate the maximum population growth rate for the population if the maximum growth occurs when n= k/2. give your answer to the nearest tenth.
