Figure 1.10 Describe three ways in which organisms in this figure interact with each other or with
their environment .
Sunlight
Leaves absorb light
energy from the sun.
CO2 Leaves take in
carbon dioxide
from the air and
release oxygen.
O2
Leaves fall to the
ground and are
decomposed by
organisms that
return minerals
to the soil.
Water and
minerals in
the soil are
taken up
by the tree
through its
roots.

Animals eat leaves
and fruit from the tree,
returning nutrients
and minerals to the
soil in their waste
products.

Figure 1.21b Collecting and analyzing data can lead to conclusions based upon two types of
logic: inductive and deductive reasoning. Explain why the statement “If red meat has iron in it
and beef is red meat, then beef has iron in it” is considered an example of deductive reasoning
rather than inductive reasoning.

Figure 1.22 What is a hypothesis? Use the figure to demonstrate the two important qualities of a
hypothesis.
Observation: Flashlight doesn’t work.
Question: Why doesn’t the flashlight work?
Hypothesis #1:
Batteries are dead.
Hypothesis #2:
Bulb is burnt out.
Prediction: Replacing
batteries will fix problem.
Prediction: Replacing
bulb will fix problem.
Test of prediction:
Replace batteries.
Test of prediction:
Replace bulb.
Result:
Flashlight doesn’t work.
Hypothesis is contradicted.
Result:
Flashlight works.
Hypothesis is supported.

why a scientific hypothesis is never
proven but can be supported by data
collected from experiments.
