An invasive plant gets into your garden. It spreads through andout-competes all of you plants, reducing the local diversity. Whichprinciple applies most directly?
| | character displacement |
| | sympatric and allopatric speciation |
| | random variation and stochasticity |
| | competitive exclusion principle |
A muskrat has a litter of offspring with another muskrat. Thenanother litter 7 months later, then 4 years later. Whichreproductive strategy best applies?
| | Parthenogenisis |
| | Iteroparity |
| | Semelparity |
| | Hermaphroditism |
During the North American summer, large areas of the Midwesthave very high albedo. This is likely because of
| | Fruiting plants |
| | Flooding in plains |
| | Ice formation in mountains |
| | Loss of plants in fields |
Nesting birds often display this type of distribution ordispersion pattern, often resulting from competition. (Forexample... how their nests are individually spaced)
| | Clumped |
| | Uniform |
| | Random |
| | Linear distribution |
The energy from the sun must be directly converted into chemicalenergy by heterotrophs for living organisms to use it.
| | True |
| | False, it must be converted by chemotrophs |
| | False, it must be converted by phototrophs |
Which of the following is a characteristic of a K-selectedspecies
| | High reproductive rate |
| | Typically found in temporary habitats |
| | Late sexual maturity |
| | Minimal parental care |
| | After the formation of continents one billion years ago, therehave been no occurrences of primary succession. |
| | There is virtually no soil at the start of primary succession,and thus it must be made before many plants can be sustained. |
| | There is a fast recovery time at the beginning of primarysuccession. |
| | It will often be triggered after a fire. |
