Bell Ringers: Week of 24 Aug – 28 Aug 2009
Monday As we move up an energy or biomass pyramid, the top
levels get smaller like an Egyptian pyramid. Label an energy
pyramid identifying organism types in each trophic level with
the energy distributions and explain why the top levels get
smaller.
Explain.
Tuesday Your friends sister is learning about symbiotic relationships and she understands that there are
three main kinds of symbiotic relationships 1) commensalism, 2) mutualism, and 3) parasitism; but she can’t
remember how to distinguish these relationships. Write a short explanation that is easy to remember.
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?
