Energy and Matter in Your Organism XX
A. Use an explanation, diagram, model or demonstration of your choice to show the
path that a labeled carbon atom (in a molecule of atmospheric carbon dioxide CO2 )
would take before it ends up in your critter as part of its muscles or other structures.
Your diagram should have the following:
1. Matter source for each step
2. Energy source for each step
3. Type of metabolic process in each step (breakdown/biosynthesis)
4. Names of metabolic processes that occur (photosynthesis/respiration, etc)
To be successful, you will need to know:
 What is the matter (think food) that your Organism XX uses for energy.
 How your Organism XX obtains this matter from its surroundings.
 Where the “food” gets its energy and in some cases where the food’s food gets
energy.
 Once the matter is ingested, how does your Organism XX process it?
 Once the matter is processed, how is the energy stored and made available for
your Organism XX’s activities.
 How Organism XX turns nutrients into something usable by the body
 What Organism XX’s body parts are made of.
B. You will need to answer the following questions to complete your project. Please type
them up on a separate page and attach them to the back of your diagram
1.
Could all the reactions in the scenarios take place within the human body?
2. What is the ultimate source of energy for the necessary events?
3. Explain the transfer of energy during these events.
4. How will biosynthesis play a role in the fate of the carbon atom?
5. Suggest a way in which the labeled carbon in the last step of your sequence could
complete the cycle and find its way back into a labeled carbon dioxide molecule in the
air.
Your representation of the carbon cycle should be at least as big as a 8 ½ x 11 piece of
paper. Everything should be neatly labeled and color is preferable to black and white.

Diagram of carbon atom pathway is
mostly clear and organized. Source
of matter is accurately identified at
most steps. Sequence may occur in
nature and is relevant to the habitat
of Organism XX.
Diagram of carbon atom pathway
is somewhat clear but hard to
follow. Source of matter is
identified at a few steps. Sequence
may occur in nature but is
generalized and not specific to the
habitat of Organism XX.
Source of energy is accurately
identified at each step. The
specific type of energy is also
identified.
Source of energy is accurately
identified at most steps. The type of
energy is identified, but lacks detail.
All steps of breakdown and
synthesis labeled correctly. All
metabolic processes identified
and labeled correctly.
Most steps of breakdown and
synthesis labeled correctly. Most
metabolic processes identified and
labeled correctly.
Source of energy is identified at a
few steps. The type of energy may
or may not be identified correctly.

Beginning
Diagram of carbon atom pathway
is difficult to follow. Source of
matter is not identified correctly.
Sequence does not resemble
anything that would occur in

No Work = No Evidence
Source of energy is not identified
correctly. The type of energy is
not identified correctly.
No Work = No Evidence
Some steps of breakdown and
synthesis labeled correctly. Some
metabolic processes identified and
labeled correctly.
An attempt was made to label the
steps of breakdown and synthesis
and name the metabolic processes
involved.
No Work = No Evidence
