-------------------------------------------------------A scientist wanted to test the effects of music on the
growth of radishes. Plants are grown from seed in
identical soil and are exposed to the same conditions. One
group of plants is exposed to classical music for 12 hours
each day. Another group is exposed to country music. A
third group is exposed to jazz and a fourth is exposed to
heavy metal. The last group is not exposed to any music.
The plants are measured weekly and their height is
recorded.

of these
sources has the strongest impact on the type of
vegetation?

homeotherms exhibit when temperatures are on either
end of their
range of tolerance.
16. Give an example of animals that demonstrate Bergmann’s
Rule &

Rule? Why or
why not?
------------------------------------------------------------1. List the 2 main factors that determine the amount of
moisture held by
the soil.
2.
Know the following vocabulary terms:
compost, humus, fertilizer, leaching, weathering
3.
What effect does farming have on soil quality?
4. Compare & contrast organic fertilizers with synthetic
fertilizers.

6. List the 3 primary nutrients that plants require.
Which is usually the
limiting nutrient? What are some other nutrients
required by plants? What is the source of most soil
nutrients in nature?
7. What environmental conditions are required to produce
compost?
