| 8415523051 | Three types of population distribution | Random, Uniform, Clumped | 0 | |
| 8415523052 | Density Dependent Factor | A factor that influences an individuals probability of survival and reproduction in a manner that depends on the size of the population (i.e. predation, disease, food supply) | 1 | |
| 8415523053 | Density Independent Factor | A factor that has the same effect on a individual's probability of survival and reproduction at any populations size | 2 | |
| 8415523054 | exponential growth models | occurs when populations are not limited by resources. (J-curve) |  | 3 |
| 8415523055 | logistical growth model | occurs when populations reach a carrying capacity established by a limiting resource and initially experience large growth but then level off. However, they do not exist exactly at carrying capacity. They fluctuate above and below. |  | 4 |
| 8415523056 | Type I, II, III Curves | reproductive strategies of different species. Type I fosters their young, Type II does sorta kinda, and type III straight up ditches their kids |  | 5 |
| 8415523057 | K selective strategies | A species with a low intrinsic growth rate that causes the population to increase slowly until it reaches carrying capacity (TYPE I) | 6 | |
| 8415523058 | R selective strategies | A species with a high intrinsic growth rate that causes the population to overshoot and quickly die off (TYPE III) | 7 | |
| 8415523059 | Population size | The total number of individuals within a defined area at a given time | 8 | |
| 8415523060 | Population density | The number of individuals per unit area at a given time | 9 | |
| 8415523061 | Population distribution | How individuals are distributed with respect to one another | 10 | |
| 8415523062 | Population age structure | how many individuals fit into age categories. Shown by age structure diagrams |  | 11 |
| 8415523063 | Growth Rate | The number of offspring an individual can produce in a given period of time, minus the deaths of the individual or offspring during the same period | 12 | |
| 8415523064 | Competition | The struggle of individuals to obtain a limiting resource | 13 | |
| 8415523065 | Resource partitioning | Where species work together and divide up a resource like birds in a tree-this can reduce competition | 14 | |
| 8415523066 | Predation | The use of one species as a resource by another species | 15 | |
| 8415523067 | Parasites | Type of predation when species live on or in the organism they consume | 16 | |
| 8415523068 | Mutualism | A type of interspecific interaction where both species benefit | 17 | |
| 8415523069 | Commensalism | A type of relationship in which one species benefits but the other is neither helped nor hurt | 18 | |
| 8415523070 | Primary Succession | Occurs on surfaces that are initially devoid of soil. Starts with moss and lichens on the exposed rock and it it progresses to shrubs and plants and eventually restores ecosystem. | 19 | |
| 8415523071 | Secondary Succession | Occurs in areas that have been disturbed but have not lost their soil | 20 | |
| 8415523072 | Community Ecology | The study of the interactions between species in a habitat | 21 | |
| 8415523073 | Competitive exclusion principle | two species competing for the same limited resource cannot coexist. This explains why resource partitioning takes place so that both can survive | 22 | |
| 8415523074 | Interspecific Competition | When two species compete over one limited resource | 23 | |
| 8415523075 | Intraspecific Competition | When two individuals within the same species compete over one limited resource | 24 | |
| 8415523076 | Factors that determine species richness | Latitude (distance from equator), Time (older the habitat, the higher SR), Habitat size (larger=greater) | 25 | |
| 8415523077 | Theory of Island Biogeography | Explains that both habitat size and distance from other land determine species richness | 26 | |
| 8415523078 | How does the human population not have a food deficit? | Innovation and Technology | 27 | |
| 8415523079 | growth rate equation | CBR-CDR/10 | 28 | |
| 8415523080 | doubling time for a population equation | 70/growth rate | 29 | |
| 8415523081 | Demography | The study of human populations and population trends | 30 | |
| 8415523082 | Total Fertility Rate (TFR) | estimate of the average number of children each woman will bear in her lifetime | 31 | |
| 8415523083 | Replacement level fertility (RLF) (developed nations) | 2.1 | 32 | |
| 8415523084 | Replacement level fertility (RLF) (developing nations) | 2.5 | 33 | |
| 8415523085 | Developed Countries | Countries with high levels of industrialization and income | 34 | |
| 8415523086 | Developing Countries | Countries with relatively low levels of industrialization and income | 35 | |
| 8415523087 | Life Expectancy | The average number of years that an infant born in a particular year in a particular country can be expected to live, given the current average life span and death rate of that country | 36 | |
| 8415523088 | Infant Mortality Rate | Number of deaths of children under the age of one per 1000 births | 37 | |
| 8415523089 | Child Mortality Rate | Number of deaths of children under the age of five per 1000 births | 38 | |
| 8415523090 | Demographic Transition | The theory that as a country moves from a subsistence economy to and industrialized one, it undergoes a predictable shift in population growth | 39 | |
| 8415523091 | Family Planning | Regulating the number or spacing of children through the use of birth control | 40 | |
| 8415523092 | IPAT equation | environmental Impact=Population, Affluence, Technology | 41 |
