Ally is a junior high student who has just learned about the carbon cycle in school. She is concerned about the environment and decides to construct a model of the carbon cycle in her community.
What could both add and remove carbon from the atmosphere in the model?
a car
a deer
an insect
a tree
Which statement about the carbon cycle is most true?
Energy is destroyed when organic matter decays.
The total mass of carbon on Earth is always increasing.
Carbon is lost from the cycle when it enters the atmosphere.
Carbon changes form, but the total amount on Earth remains the same.
A student is drawing a model of the carbon cycle. Which caption should he include to explain how herbivores contribute to the carbon cycle from the food they eat?
Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.
Herbivores eat plants, producing carbon dioxide during photosynthesis that is released into the atmosphere.
Herbivores use carbon dioxide from the atmosphere to produce oxygen during cellular respiration.
Herbivores use oxygen from the atmosphere to produce carbon dioxide during photosynthesis.
Which parts of the carbon cycle is shown in the illustration?
cellular respiration and decomposition
combustion and decomposition
decomposition and photosynthesis
photosynthesis and cellular respiration
Which arrow represents cellular respiration?

All living organisms contain carbon. As organisms grow, they require large quantities of carbon to carry out life processes and make new cells. Where is the source of most of Earth's available carbon?
Carbon is constantly recycled from dead organisms back into the environment.
New carbon atoms are constantly being created by the process of photosynthesis.
Carbon atoms are constantly transferred from the Sun to Earth along with sunlight.
Carbon is constantly transported from the mantle to the crust by volcanic eruptions.
Which of the following processes removes carbon dioxide from the atmosphere?
Photosynthesis
Cellular Respiration
Combustion
Decomposition
During cellular respiration, glucose is broken down to produce energy. What are the main products of this process?
Oxygen and Water
Carbon Dioxide and Water
Glucose and Oxygen
Carbon Dioxide and Glucose
In the carbon cycle, which of the following is a major way carbon is returned to the atmosphere?
Photosynthesis
Cellular Respiration
Absorption by oceans
Formation of fossil fuels
