| 897371363 | Population Total (the variable that represents it) | N | |
| 897371364 | Biotic Potential | Maximum growth rate of an organism under ideal conditions and unlimited resources | |
| 897371365 | Growth rate depends on an organism's... | •Reproductive span •Amount of offspring/ brood size •Survivability to reproductive age •Age to reproduction •# of times of reproduction/year | |
| 897371366 | Carrying Capacity | Number of organisms an ecosystem can sustain | |
| 897371367 | Example of density dependent limiting factors | •Toxic effect of waste •Competition for food, space, sunlight •Disease | |
| 897371368 | Example of density independent limiting factors | •Natural disasters •Climate change | |
| 897371369 | r (what the variable represents) | Growth rate | |
| 897371370 | Growth of a population | r= births-deaths --------------------(divided by) N (population at beginning of study) | |
| 897371371 | Exponential Growth | r > 0 | |
| 897371372 | Logistic Growth | r = 0 | |
| 897371373 | r selected species | •high rate of population •opportunistic •no parental care | |
| 897371374 | K selected species | •maintain a relatively constant population |
