| 9433307109 | population | A group of individuals that belong to the same species and live in the same area | 0 | |
| 9433307110 | age structure | Percentage of the population (or number of people of each sex) at each age level in a population. | 1 | |
| 9433307111 | population density | Number of individuals per unit area | 2 | |
| 9433307112 | exponential growth | Growth of a population in an ideal, unlimited environment, represented by a J-shaped curve when population size is plotted over time. | 3 | |
| 9433307113 | carrying capacity | Largest number of individuals of a population that a environment can support | 4 | |
| 9433307114 | density dependent | factor that limits population growth and has greater effect in dense populations than less dense populations | 5 | |
| 9433307115 | density independent | limiting factor that affects all populations in similar ways, regardless of population size | 6 | |
| 9433307116 | limiting factor | Any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of organisms. | 7 | |
| 9433307117 | logistic growth | When limiting factors restrict size of population to the carrying capacity of the environment. Forms an S-shaped curve. | 8 | |
| 9433307118 | k-selected species | Species that produce a few, often fairly large offspring but invest a great deal of time and energy to ensure that most of those offspring reach reproductive age. | 9 | |
| 9433307119 | r-selected species | Life history traits maximize reproductive success in uncrowded environments. Many small offspring that mature quickly, little if any parental care. | 10 | |
| 9433307121 | survivorship curve | a graph showing the decline in numbers of a cohort over time |  | 11 |
| 9433307124 | Population Distribution | How individuals in a population are spaced out across the range. | 12 | |
| 9433307125 | Growth Rate | This determines whether the size of the population increases, decreases, or stays the same. | 13 | |
| 9433307127 | 1) Birth Rate 2) Death Rate 3) Immigration 4) Emigration | 4 Factors that Affect Population Growth? |  | 14 |
| 9433307131 | Immigration | The movement of individuals INTO an area. This can cause a population to grow. | 15 | |
| 9433307132 | Emigration | The movement of individuals OUT of an area. This can cause a population to decrease in size. | 16 | |
| 9433307140 | Density dependent factors | 1) Competition 2) Predation 3) Parasitism and Disease 4) Stress from overcrowding |  | 17 |
| 9433307141 | competition | Organisms fight for water, space, sunlight, and other resources. Increases as population size increases. |  | 18 |
| 9433307143 | Density independent factors | 1) Weather 2) Natural Disaster 3) Seasons 4) Human Activities |  | 19 |
