chapter 43

What substance would you expect to accumulate in soil as a result of increased acid precipitation? Ammonia
Temperature is perhaps the most important factor in the distribution of organisms because most organisms are unable to regulate their body temperature precisely.
How do corals react when water temperatures are too high? They expel their symbiotic algae.
The northern boundary of the distribution of wild madder is defined by areas that do not go below 4.5 Celsius.
The serotinous cones of the longleaf pine, Pinus palustris, depend on _____ to release their seeds. fire
What naturally occurring process is responsible for keeping the earth warm enough to sustain life? Greenhouse effect
The Earth's surface releases __________ that is absorbed by the atmosphere, stabilizing or raising atmospheric temperature. long-wave infrared radiation
What will be a consequence if current predictions of global warming are accurate? Organisms will need to migrate or adapt quickly in order to survive.
What is most likely to be a common adaptation of coastal plants that grow on sand dunes? deep roots to extract moisture.
In aquatic environments, at what range does photosynthesis take place? 0-100 m
. Why are red algae found in deeper oceanic waters? They possess pigments that allow them utilize blue-green-light.
In arid terrestrial environments, salt can accumulate in the soil because of the settlement and evaporation of water.
The optimal pH range for most freshwater fishes and invertebrates is 6 - 9.
The sea heats and cools more slowly than the land.
The global patterns of atmospheric circulation and precipitation occur because of rising masses of warm air and sinking masses of cool air
What is adiabatic cooling? cooling due to the decrease in air pressure at higher elevations
Currents in the ocean basins of the Northern Hemisphere always run in what direction? clockwise
Most of Europe is in the ______ biome. temperate deciduous forest
How would you best explain the existence of a mountain range which runs east-to-west and has abundant conifer trees, ferns, and mosses on the east side, but only sparse shrubby plants on the west side? Precipitation differences due to a rain shadow on the west side produce the differing plant communities.
Which of the following is a characteristic of tundra? dry climate
What factor would you expect to show the largest difference between the coral reef and intertidal biomes? Temperature variation
The Earth is spherical, which causes differences in the intensity of solar radiation at different latitudes (refer to Figure 43.14 ). The Earth is also tilted on its axis at a 23.5 angle. How do you think this tilt affects the intensity of solar radiatio The sun's rays strike the Northern hemisphere more obliquely during its winter months and less obliquely during its summer months.
Which organism would be most likely to be able to survive rapid global climate change? an insect that can feed upon many different plant species
Based on the three cell model of global air circulation shown in the figure above, where would you be most likely to find a plant species that is very drought tolerant, but not cold tolerant? between 20 and 30 latitude
