Which of the following removes carbon from the atmosphere?

• Combustion

• Respiration

• Photosynthesis

• Death

What is happening at 1?

• respiration: releasing CO₂

• decomposing CO₂ in the soil

• photosynthesis: absorbing CO₂

• turning CO₂ from the atmosphere into organic molecules

The diagram shows the flow of organic molecules through an ecosystem. What two processes are identified by the labels X and Y?

• X : Respiration Y : Predation

• X : Adaptation Y : Decomposition

• X : Fermentation Y : Nitrogen Fixation

• X : Decomposition Y : Respiration

What process occurs when coal (fossil fuel) is used for energy?

• Decomposition

• Combustion

• Pressurization 

• Respiration 

What does NOT produce carbon dioxide?

• Photosynthesis

• Burning Fossil Fuels

• Animal respiration

• Plants decaying

12D: This diagram demonstrates why the ocean is a large carbon sink. An increase in the amount of carbon dioxide in the atmosphere can cause atmospheric temperatures to increase. Which statement explains how this could affect the ocean as a carbon sink?

• Less atmospheric carbon dioxide would be available to phytoplankton

• Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for gas

• Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean

• Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperatures would cause ocean temperatures to increase

12D What would be the most likely effect of a wildfire that burned a large area of a forest? AND what cycle would it affect the most?

Living organisms need nitrogen to make: Select all that apply.

• food

• sugar/phosphate backbone

• Proteins

• DNA bases

• Amino acids

What converts nitrogen into a useable form for plants and animals?

• bacteria

• fungi

• rain

When nitrogen gas is turned in to a form that plants and animals can use is called 

• Combustion

• Photosynthesis

• Decomposition

• Nitrogen Fixation
