| Question | Answer |
|---|---|
| The average year after year conditions of temperature and precipitation in a particular region are referred to as the region's | climate |
| all of the following factors contribute to earths climate except (latitude,longitude,transport of heat,shape and elevation of landmasses) | longitude |
| climate is a global factor that produces | a wide range of environmental conditions that shapes communities |
| temperatures on earth remain within a suitable range for life as we know it because of the | greenhouse effect |
| the loss of heat to space is slowed by | atmospheric gases |
| the greenhouse effect is | the result of an excess of carbon dioxide in the atmosphere |
| earth had three main climate zones because of the differences in latitude and, thus | angle of heating |
| cool air over the poles will | sink |
| the unequal heating of the earths surface | drives wind and ocean currents |
| the tendency for warm air to rise and cool air to sink results in | global wind patterns |
| which of the following climate scenarios might be found around the himalayas, the tallest mountains the the world? | TEXT JAYCIE ABOUT #11 |
| why does earth have three main climate zones? | there are differences in latitude and thus the angle of heating from the sun |
| each of the following is an abiotic factor in the environment except (plant life,rainfall,soil type,temperature) | plant life |
| which is a biotic factor that affects the size of a population in a specific ecosystem? | number and kinds of predators in the ecosystem |
| an organisms niche is | the range of physical and biological conditions in which an organism lives and the way in which it uses those conditions |
| several species of warblers can live in the same spruce tree only because they | occupy different niches within the tree |
| a wolf pack hunts, kills, and feeds on a moose. in this interaction, the wolves are | predators |
| different species can share the same habitat, but competition among them is reduced if they | occupy different niches |
| no two species can occupy the same niche in the same habitat at the same time | because of the competitive exclusion principle |
| a symbiotic relationship in which both species benefit is | mutualism |
| the symbiotic relationship between a flower and the insect that feeds on its nectar is an example of | mutualism because the flower provides the insect with food and the insect pollinates the flower |
| a predator can increase the numbers of certain species in its habitat by | killing and eating the competitors of other species |
| the series of predictable changes that occurs in a community over time is called | ecological succession |
| primary succession can begin after | a lava flow |
| what is one difference between primary and secondary succession? | secondary succession begins on soil and primary succession begins on newly exposed surfaces |
| which factors and influence continual change in an ecosystem?(further disturbances,long term climate changes introduction of nonnative species,all of the above) | all of the above |
| which of the following occurs during the ecological succession of a ecosystem? | living organisms modify their environment a little at a time |
| which is a factor that could interrupt the progress of succession? | another natural disturbance |
| climate conditions in a small area that differ significantly from the climate of the surrounding area called | microclimates |
| An example of a place with a microclimate is | a forested park in a desert city |
| which of the following can influence the climate in a small area within a biome? | natural features such as a lake |
| which biome is characterized by very low temperatures, little precipitation, and permafrost? | tundra |
| which two biomes have the least amount of precipitation? | tundra and desert |
| a biome is identified by its particular set of abiotic factors and its | characteristic ecological community |
| aquatic ecosystems are classified by all of the following except (depth and flow of the water,temperature of the water,organisms that live there,chemistry of the water) | organisms that live there |
| which one of the following statements is not true of freshwater wetlands? | the water in freshwater wetlands is always brackish |
| ponds and lakes are | standing-water ecosystems |
| what is one way a wetland ecosystem differs from a standing-water ecosystem? | water does not always cover a wetland as it does a standing-water ecosystem |
| the photic zone | extends to a depth of about 200 meters |
| what is not true about the open ocean | the open ocean does not begin at the low-tide mark or extend to the end of the continental shelf |
| the energy of incoming____________drives earths weather and helps to determine climate | sunlight |
| regrowth of grasses,ferns,wildflowers, and saplings after a forest fire is an example of______________succession | secondary |
| atmospheric gases that trap heat inside earth's atmosphere are called___________gases | greenhouse |
| organisms within an ecosystem are_____________factors in that ecosystem | biotic |
| over time,some plants growing in an area are crowded out by other plants. the new plants are crowded out by other plants. the new plants use up water and nutrients needed by the previous plants. the disappearance of the first plants is due to____________ | competitive exclusion |
| list 5 factors that contribute to global climate patterns | -greenhouse effect -latitude -transport of heat by wind and ocean currents -resulting amount of precipitation -shape and elevation of land masses |
| list three biotic and three abiotic factors that determine the survival of a rabbit in a temperate forest | Biotic_shrubs,trees,nuts Abiotic_water,sunlight,temp. |
| describe an important role that pioneer species play in primary succession | they are the first species in an area so they help other species acclimate to the environment |
