Isle Royale is located in Lake
Superior. Isle Royale is home to
populations of wolves and moose.
The interactions between the
wolves and moose, as well as the
individual population sizes, have
been studied since 1958. The
graph shows the population sizes
over time for both wolves and
moose.
1. Describe one limiting factor for the moose population.
2. Explain one likely reason why the wolf population rapidly increased
between 1975 and 1980.
3. Predict what will happen to the moose population’s size after 1994 by
describing the shape of the curve. In your answer, be sure to explain
the reasoning behind your prediction.
Answer
1. Possible limiting factors could be: predation, habitat
destruction, shelter/natural disturbances/water supply.
Include an explanation of the limiting factor in your
answer
2. The wolf population rapidly increased between 1975 and
1980 because there was an ample food supply. From
1970-1975, the moose population was at a high level.
Because wolves prey on moose, there was an ample food
supply to support a larger wolf population.
3. Possible answers: moose population will drop and level
off around 1400-1200. Because they live on an island
there are a limited amount of resources available. OR The
moose population will drop below 1,000 if the wolf
population increases. The increase in the wolf population
would be due to the increased availability of moose,
which would result in a decline in the moose population.

Use the information provided to answer the questions
below.
Use complete sentences!
1. Describe the general composition of a
protein molecule.
2. Describe how the structures of proteins differ
from the structures of carbohydrates.
3. Describe how the functions of proteins differ
from the functions of carbohydrates.
Answer
1. Proteins are composed of amino acid molecules linked
together by peptide bonds. C, H, N, S, and O are typical
atoms that compose amino acids.
2. The amino acids contain amino and carboxyl groups.
Primary, secondary, tertiary, and quaternary structures of
a protein molecule are necessary for the protein to
function correctly. Interactions occur between amino and
carboxyl groups of amino acids. Carbohydrates are
composed of C, H, and O. Monosaccharides are the
building blocks of carbohydrates. Two monosaccharides
form a disaccharide. Many monosaccharides form a
polysaccharide, such as starch, cellulose, or chitin.
3. Proteins function as enzymes, antibodies, and structural
components. Carbohydrates function in short-term
energy storage (starch, glycogen) or structural
components (chitin, cellulose, glycogen)
