A population is a group of individuals belonging to - species that interact with one another. The total number of individuals in a population is the - . On the other hand, the number of individuals per unit area is the - . - ANS-one poluation size population density A population of 200 deer is reintroduced to a forest after many years of being absent. This population is tracked for the next 50 years. Based on the following data of the first 50 years, and assuming that there is no resource limitation, how many deer would you expect to find in this population 60 years after their introduction? - ANS-1,600 deers A population of 350 ants inhabits a single tree in a forest. One hundred of the ants migrate to a nearby tree but remain in the same population. No new ants are produced in this process. Which of the following measures changed when the ants invaded the new tree? - ANS-population density A population of deep sea crabs lives in marine worm burrows and eats decaying matter falling from shallow-water biological communities above. Which of the following would likely decrease the carrying capacity of these seafloor crabs? - ANS-pollution disrupting the shallow-water biological communities above the crab habitat invation of a fish that preys on worms A population of paramecia grows from 16 to 64 in six days. What is the doubling time for this population? - ANS-3 days A population of paramecia grows from 16 to 128. How many generations, or doubling times, has this population undergone? - ANS-3 A population size can be much lower than the carrying capacity for an extended period of time. - ANS-t Among the four populations described below, which has the largest population size, and which has the largest population density? Each Selection is only used once. - ANS-large populations size: A population 200 frogs living in a 200 square foot pond large population density: A population of 50 ants living in a one square foot burrow Based on the graph below of a population of goats over the 50 years since they were introduced to an island, what is the likely carrying capacity of the island for the goats? - ANS-300 Consider a population of birds, living in a forest, that nest within the branches of oak trees and feed on beetles and earthworms. Which of the following would like
