| 7888438105 | Survivorship curve | Shows how the likelihood of death can vary with age | 0 | |
| 7888446723 | Type I | Survival rates are high when organisms are young and decrease sharply when organisms are older EX. Human | 1 | |
| 7888453204 | Type II | Survival rates are equivalent regardless of an organisms age EX. Birds or mice | 2 | |
| 7888461165 | Type III | Death takes place at young ages, and surviving rates are greater when they are older EX. amphibians or trees | 3 | |
| 7888551878 | Logistic curve |  | 4 | |
| 7888595807 | J curve |  | 5 | |
| 7888604946 | R- selected organism | Focus on quantity, not quality: small size, fast development, short lived, reproduction in early life, many small offspring, no parental care EX. Mice, rabbits, weeds, bacteria | 6 | |
| 7888610136 | K-selected organisms | Low biotic potential with a relatively small number of offspring and take a long time to raise their young: large size, slow development, long lived, reproduction in later life, few large offspring, slow population rate EX. Giraffes, elephants, humans | 7 | |
| 7888617550 | Density independent | Factors are limiting factors whose influence is not affected by population density. EX. Floods, fires, landslides | 8 | |
| 7888623907 | Density dependent | Limiting factors whose influence is affected by population density. EX. Food- more dense population = greater struggle to get food | 9 | |
| 7888635299 | Habitat | Specific enviroonment in which an organism lives | 10 | |
| 7888643289 | Niche | A species' niche reflects its use of resources and its functional role in community | 11 | |
| 7888651618 | Population distribution | -Random -Uniform -Clumped | 12 | |
| 7888659967 | Describe predator prey relationships and curves | A predator prey relationship is when the prey's population grows exponentially and then so does the predator. This is because more prey becomes available, so their population goes up as well. The predators population will folllowe the prey's, but at a different rate. | 13 | |
| 7888669762 | What is the world population today | 7.6 billion | 14 | |
| 7888674482 | How has the world population changed over the last 10-12,000 years | Over the last 10-12000 years the population has increased. This is because we are becoming more advanced and people are healthier and live longer, so the world is starting to become over populated. We are in an exponential growth phase. | 15 | |
| 7888683233 | In a population of 50,000 individuals the birth rate is 52 out of 1000 individuals and the death rate is 14 out of every 1000 individuals. What is the growth rate of this population? How many people will be added to or deleted from the population in one year? | B=52/1000=.052 D=14/1000=.014 .052 - .014 = .038 X 50000 = 19000.000 increase per | 16 | |
| 7888689908 | Immigration | Arrival of individuals from outside the population | 17 | |
| 7888694174 | Emigration | Departure of individuals from the population | 18 |
