Biogeochemical Review

How are the processes of Cellular Respiration and Photosynthesis are related?

• the products of cellular respiration are the reactants of photosynthesis
• the products of cellular respiration and photosynthesis are the same
• the reactants of photosynthesis and cellular respiration are the same 
• both processes are performed in the same organelle 

What is the role of autotrophs in the carbon cycle?

• autotrophs take in carbon as CO2 and make glucose from it
• autotrophs release CO2 into the atmosphere
• autotrophs make carbon 
• autotrophs destroy carbon

Which statement best describes the role of heterotrophs in the carbon cycle?

• heterotrophs take in carbon as CO2 and make glucose from it
• heterotrophs release CO2 into the atmosphere
• heterotrophs make carbon 
• heterotrophs destroy carbon

The process of decomposition...

• breaks down organisms, releasing CO2 into the atmosphere
• puts toxins in lakes and rivers
• is only done by plants
• causes acid rain

CO2 is called a 'green house gas' because...

• CO2 helps plants grow
• CO2 traps heat and warms the earth
• CO2 is a green color
• CO2 is released by greenhouses
