| Question | Answer |
|---|---|
| The _______ Rate of Increase (r) determines the ______ size of a population based on current factors | Intrinsic; Future |
| The Intrinsic Rate of Increase is written as ____ | r |
| Immigration, Emigration, Number of births, number of death and n (current number of population) are all influences on the Intrinsic Rate of ______, aka ____ | Increase; r |
| Individuals ENTERING the population from other populations | Immigration |
| Individuals LEAVING the population to go to other populations | Emigration |
| n= the _______ number in the population | Current |
| To calculate r, the Intrinsic Rate of Increase the formula is: ___ - ___ / n | # Births; # Deaths |
| If r is positive, the population is expected to ____ over time | Grow |
| If r is negative, the population is expected to _____ over time | Decline |
| The Exponential Growth model will occur if a population is exhibiting its _______ potential | Biotic |
| Biotic Potential means a population is at ______ growth under _____ conditions | Maximum; Ideal |
| When the number of individuals increases in a population, their ability to reproduce increases, creating an _______ growth curve | Exponential |
| Biotic potential is NOT ________ because the populations will always meet environment _______ | Realistic; Resistance |
| Examples of environment resistances that prevent biotic potential include depletion of _________ such as: food supply, habitat, new predators | Resources |
| An example of resource depletion was the _____ on St. Pauls Island where they overgrazed and damaged the environment causing them to ____ off | Reindeer; Die |
| Two types of population growth model include _______ Growth and ______ Growth | Exponential; Logistic |
| Logistic Growth is what ______ happens | Really |
| The Logistic Growth is shown by an "___" curve | S |
| If a population is small, population increase is ______ because there are fewer individuals to reproduce | Slower |
| If a population is large, population increase happens ______ because large populations have more newborns so the population increases rapidly | Rapidly |
