Review questions for the test
| Question | Answer |
|---|---|
| The type of graph you'd expect if you graphed hourly wage. | Linear |
| The type of graph you'd expect if you graphed bacterial growth, with no limiting factors. | Exponential |
| What letter is used to symbolize carrying capacity? | K |
| The number of organisms an environment can support is the | carrying capacity |
| Animals that show slow reproductive patterns are | humans, horses, elephants (large animals!) |
| Animals that show fast reproductive patterns are | insects, rodents (small animals) |
| Characteristics of fast reproducers are | small body size, short life span, low tolerance for change, produce many offspring |
| Characteristics of slow reproducers are | large body size, long life span, high tolerance for change, produce fewer offspring |
| What are limiting factors? | Things that limit an organisms ability to live, reproduce, inhabit, takeover, be successful in an environment |
| What are examples of limiting factors? | temperature, food, water, territory, mates, all resources |
| What are examples of density-dependent factors? | disease, parasites |
| What are examples of density-independent factors? | flooding, fires, natural disasters |
| How is a growth rate calculated? | The difference between the number of births and the number of deaths. |
| What is immigration? | Individuals moving into a population. |
| What is emigration? | Individuals moving out of a population. |
| What is the study of population characteristics? | Demography |
| What is a coastal body of water partially surrounded by land? | Estuary |
| What force causes the tides? | Gravity |
| Where can you find the intertidal zone? | Tidepools! The area between the high tide mark and the low tide mark. |
| Where is the subtidal zone? | Just below the intertidal zone. |
| What does aphotic mean? | without light (like the deep parts of the ocean) |
| What are characteristics of the shallow parts of a lake? | Lots of nutrients, sunlight, organisms (fish, invertebrates, plants) |
| What happens on the bottom of the lake? | Decay and recycling of organisms with the help of bacteria. |
| This biome is characterized by a tropical wet season and dry season. It has few trees. Animals such as giraffes, hyenas, and zebras. | Savanna |
| This biome is characterized by harsh winters and cold summers. Has no trees but lots of shrubby ground cover. Reindeer and arctic fox live here. | Tundra |
| This biome is characterized by cold winters and hot summers. Good soil for leafy trees like maples and oaks. Raccoon, deer, and songbirds live here. | Temperate deciduous forest. |
| This biome is characterized by cold, snowy winters and cool summers. Coniferous trees dominate the landscape. Moose, fishers, and lynx live here. | Taiga |
| This biome is characterized by cold winters and hot summers. There are no/few trees. The soil is rich. Animals like bison, prairie dogs, and pronghorn antelope live here. | Temperate grassland. |
| This biome is characterized by excessive precipitation. The soil is nutrient poor. It is the most biologically diverse. | Tropical rain forest |
| This biome is characterized by an excessive lack of precipitation. It is often hot during the day and cool/cold at night. Succulent plants can be found here. | Desert |
| This biome is found in coastal regions in southern California and around the Mediterranean. It is a dry area with spiny shrubs and rocky soil. Jackrabbits, kit fox, pumas, and wild goats can be found here. | Chaparral |
