If you were told that there were 350 deer in an area that covers 10 square kilometers, how would you calculate the population density of the deer? | You would divide the total population (in this case, 350 deer) by the area of land the population inhabits (in this case, 10 square kilometers) to get the population density (in this case, 35 deer per square kilometer) |

The movement of organisms into a given area from another area is called ____. | immigration |

When organisms leave a certain area, the movement is called ___. | emigration |

For a population to grow, the ____ rate must be bigger than the ____ rate | birthrate must be larger than the deathrate |

When individuals reproduce at a constant rate, ____ growth occurs. | exponential (For example, bacteria dividing at a constant rate of once every 20 minutes can create a colony of over a million bacteria from one original bacterium in less than 7 hours) |

The various growth phases through which most populations go are represented on a(an) ____. | logistic growth curve |

As resources in a population become less available, the population will ___. | reach its carrying capacity |

In a logistic growth curve, exponential growth is the phase in which the population ___. | grows more and more quickly |

When the exponential phase of a logistic growth curve of a population ends, the ____. | population continues to grow, but at a slower and slower rate. |

The number of individuals per unit area is a populationâ€™s ____. | density |

Logistic growth occurs when a populationâ€™s growth __________ , after a period of rapid growth. | slows down or stops |

Under conditions of logistic growth, population size will rise and fall around an average point called the ____. | carrying capacity |

A map that highlights the areas of the world where a population of one species can be found is describing the species' _______. | geographic range (The map below shows the geographic range of different rattlesnake species in the United States), |

Under ideal conditions with unlimited resources, a population will grow _____. | exponentially, |

The graph of exponential population growth is described as a(n) _____-shaped curve. | J-shaped curve, |

The graph of logistic population growth is describes as a(n) _____-shaped curve. | S-shaped, |

Which type of population growth does this graph show?, | Exponential growth (which only happens under ideal conditions with unlimited space, food and no predators), |

Which type of population growth does this graph show?, | Logistic growth, |

At which point in the graph below is the population growth rate accelerating?, | Point A, |

At which point in the graph below is the population growth rate the highest?, | The population growth "rate" is the highest at point B (Notice that the slope at point B is the steepest. The slope, rise over run, equals population growth/rise divided by time/run, which equals the population growth "rate"), |

At which point in the graph below is the population growth rate slowing down?, | Point C, |

At which point in the graph below is the population the highest?, | The population is the highest at point D (look along the y-axis), |

At which point on the graph below is the population growth rate the lowest?, | The population growth rate is lowest at point D (notice that the population, even though it is at its highest, has stopped growing), |

At which point in the graph below is the population at the carrying capacity?, | The population has reached the carrying capacity at point D (Remember, the carrying capacity is the maximum number of individuals that the environment can support), |

Which type of population distribution pattern is shown below?, | Clumped (This type of distribution pattern is often found among species that stick together to avoid predation or that hunt in packs), |

Species that stick together to avoid predation or that hunt in packs would show a(n) ______ population distribution pattern. | clumped, |

Which type of population distribution pattern is shown below?, | uniform (This type of distribution pattern is usually found when members of a population compete with each other for space or other resources), |

Species that compete for space or other resources would show a(n) ______ population distribution pattern. | uniform, |

Which type of population distribution pattern is shown below?, | Random (This type of distribution pattern is usually found when the location of an individual in a population is independent of the other individuals), |

Species that live in populations where the location of an individual is independent of the other individuals would show a(n) ______ population distribution pattern. | random, |
