| When species evolve in response to each other | coevolution |
| A close long-term relationship between species | symbiosis |
| In parasitism, one species is the parasite the other is the | host |
| A relationship where one species not effected and the other is benefited | commensalism |
| How a species reacts with other organisms defines it | niche |
| An organisms' job is defined as its | niche |
| What occurs when organism attempt to use the same resources | competition |
| The regular procession of species replacement in an ecosystem | succession |
| The ability of an ecosystem to resist change | stability |
| An ecosystem's diversity is determinded by two characteristics | latitude and size |
| Thorns and prickles enable plants to | discourage herbivores |
| When the niches of two species overlap and on species dies out | competitive exclusion |
| Five species of warblers can share the same spruce forest due to | different realized niches |
| The growth of weeds on rock exposed by a recent landslide is an example of | primary succession |
| When a keystone species is removed from an ecosystem the number of species in the ecosystem | decrease in number |
| The most stable ecosystems are those that are the most | diverse |
| Succession in an abandoned field is called | secondary succession |
| Succession on a newly formed island is called | primary succession |
| In the mark and recapture formula, P stands for | population |
| The P found in the mark and recapture lab represents an estimate of | the population or number of M&Ms in the bowl |
| If it was your job to count all the visible stars in the sky with in the next 10 hours, what method would you use | random sampling |
| During our tree lab, what method of gathering a number of the tree population is preferred counting or mark and recapture | count |
| Humans have no natural enemies; which curve best describes our population | J curve |
| Which curve best represents a population with no natural predators | J curve |
| Which population curve would best represent the local mice population | S curve |
| Trees with small, drab flowers are probably pollinated by | the wind |
| Ten horses and three goats kept in a very small pasture. They are in _______ for the grass | competition |
| The small barnacles ________ niche was both the deep and shallow waters | fundamental |
| The number of individulal species an ecosytem can support is called its | carrying capacity |
| True or false - an s curve is often stays way above the carrying capacity and then drops off when resources are depleted | false |
