Multiple Choice

Based on the image, what do you think the carbon cycle is?

• The carbon cycle is the method by which plants grow without sunlight.
• The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, and oceans.
• The carbon cycle refers to the movement of oxygen in the atmosphere.
• The carbon cycle is the process of water evaporation and precipitation.

Multiple Choice

Based on the image, what is decomposition?

• Decomposition is the process of cooking food.
• Decomposition refers to the preservation of organic matter.
• Decomposition is the creation of new organic materials.
• Decomposition is the breakdown of organic matter into simpler substances.

Multiple Choice

Based on the image, what is a reservoir?

• A reservoir is a natural lake for swimming.
• A reservoir is a type of fish tank.
• A reservoir is a storage area for water.
• A reservoir is a place for storing food.

​Help! The pictures are mixed up. Can you fix them?

​Cycle: a series of events that repeats over and over in a predictable pattern.

• ​the water cycle

• the rock cycle

• moon phases

• calendars

​The carbon cycle describes the movement of carbon atoms between living and nonliving things. Carbon can take several forms during the carbon cycle, including:

• carbon dioxide

• glucose

You learned how carbon atoms move between living things during photosynthesis and cellular respiration. These processes are part of the carbon cycle.

​Carbon Cycle Interactive

​As you complete the interactive, create a model of the carbon cycle using the diagram in Carbon Cycle Notes. To create your model:

• label the major carbon reservoirs;

• draw arrows to show what direction carbon moves;

• label the arrows with the name of the process that occurs; and

• use color to make your model easier to follow.

Multiple Choice

Which of the following are reservoirs in the carbon cycle?

• Deserts
• Atmosphere, oceans, soil, fossil fuels
• Mountains
• Rivers

Multiple Choice

What molecule is the primary form of carbon that is found in the atmosphere?

• carbon monoxide (CO)
• methane (CH4)
• carbon dioxide (CO2)
• carbonic acid (H2CO3)

Draw

Match each description of events in the carbon cycle to the process it describes.

• ​reservoirs are areas that hold a large amount of a substance; and

• the carbon cycle moves carbon between living and nonliving things.

​To summarize:
