Bell Ringers: Week of August 25 – 29, 2008
Monday Emily and her family live in Maine, and they have planned a road trip to travel across Canada and the
United States. They travel across Canada through forests of spruce and fir trees until they reach the west
coast. Traveling south through temperate rain forests, they reach southern California, where only shrubs grow in
dry soil. Heading east, they pass through deserts and eventually reach the deciduous forests of the east coast.
They drive northward to home. Which describes Emily’s cross-country trip?
A. Emily witnessed a series of ecosystem successions such as scrubland to desert.
B. The family spent their entire trip in the North American biological community.
C. The trip encompassed a majority of the major terrestrial biomes of Earth.
D. They traveled through several large ecosystems such as the American desert.
Explain.
Tuesday As we move up an energy or biomass pyramid, the top levels get smaller like an Egyptian pyramid.
Diagram an energy pyramid identifying trophic levels and explain why the top levels get smaller.
Wednesday Mario and several friends spend a day at the beach. While watching the ocean waves crashing to
shore, Mario wonders how much of the world’s water is contained in different types of bodies of water such as
oceans, lakes, and rivers. He decides to research the percentage of Earth’s water found in different locations.
Which does his research reveal?
A. Fifty percent of Earth’s water is in oceans and the glaciers at the poles.
B. Less than 3 percent of Earth’s water is freshwater containing no salt.
C. Ninety percent of Earth’s water is in lakes, rivers, and groundwater.
D. The ice caps located at both poles contain 30 percent of Earth’s water.
Explain.
Thursday
As soon as rock forms, as it does almost continually on the island of Hawaii, biological changes begin. Describe
some examples of plant life at each level of succession starting from new rock.
Friday
If a population grows larger than the carrying capacity of the environment what will most likely happen and why?
