Biology Ec6 Quiz Carbon Cycle

Flowing water can slowly dissolve carbon in sedimentary rock. Most of this carbon ends up in the ocean. The deep ocean can store carbon for thousands of years or more.

Which of these statements are true?

• Living organisms release carbon dioxide as a byproduct of cellular respiration.

• Photosynthesis adds carbon dioxide from the atmosphere preventing it from making organic compounds.

• Carbon dioxide is given off when dead organisms and other organic materials decompose.

• Freezing organic material, such as fossil fuels, adds carbon dioxide to the atmosphere.

Which of these statements are true?

• Carbon cycles far more slowly through geological processes such as sedimentation. Carbon may be stored in sedimentary rock for millions of years.

• Carbon dioxide is released when limestone is heated during the production of cement.

• Ocean water absorbs dissolved carbon dioxide when water temperature rises.

• When volcanoes erupt, they give off carbonic acid that is stored in the mantle.

Why is there more carbon in the atmosphere now than there has been in the past hundreds of thousands of years?

• There is more volcanic activity now than ever before.

• Burning fossil fuels has released great quantities of carbon dioxide into the atmosphere

• The use of nuclear and solar power has released great quantities of carbon dioxide into the atmosphere

• The melting of the polar ice caps is releasing stored reservoirs of carbon dioxide.

How has cutting forests and clearing land increased carbon dioxide in the atmosphere? (check every correct answer?)

• Often the clearing involves burning, which releases carbon dioxide that was previously stored in autotrophs. 

• These activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis

• Clear cutting destroys decomposers like the bacteria and fungus that absorb large amounts of carbon dioxide.

• Clearing lands increases erosion, which releases carbon dioxide from teh topsoil.
