Carbon Cycle and Law of Conservation of Energy and Mass

What are the two main reservoirs for carbon dioxide?

• Ocean, fossil fuels

• Ocean, atmosphere

• Atmosphere, fossil fuels

• Calcium Carbonate, ocean

What process involves plants taking in carbon dioxide to produce glucose?

• Combustion

• Respiration

• Decomposition

• Photosynthesis

Photosynthesis takes carbon out of ....?

• soil
• water and atmosphere
• decaying animals
• fossil fuels

Which describes a way Carbon is released back into the atmosphere?

• through precipitation

• through the burning of fossil fuels

• through assimilation

• through nitrogen fixation

What organisms in the ocean absorb the most

carbon dioxide?

• Algae and marine plants

• Ocean mammals, like whales and dolphins

• Fish

• Coral

How can the adherence to the law of conservation of mass in living systems be demonstrated through the following observations?

• The total mass of a dead organism equals the total mass of matter released to the environment by decomposition.

• Most plants and animals begin their life cycle with a smaller mass and gain mass during development.

• The total mass of all organisms in an ecosystem remains the same over time.

• Living animals must consume food with a mass much greater than the mass of their body over their lifetime.

Organisms that do not decompose can be buried and become what?

• water
• nutrients
• air
• fossil fuels

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide and removing them causes more carbon to stay in the atmosphere

• trees provide shade which counteracts global warming

• trees absorbs the sun's energy without radiating back into the atmosphere

• trees drain greenhouse gases like methane from soil

Which process in the carbon cycle involves the release of carbon dioxide into the atmosphere by plants and animals?

• Photosynthesis

• Decomposition

• Respiration

• Carbon Sequestration

What is the name of the carbon reservoir represented by the rabbit in the diagram?

• producers

• consumers

• decomposers

• detritus
