The reactions of photosynthesis and cellular respiration are often referred to as the "Carbon Cycle". Why do you think this is? Explain your reasoning.

• This is referred to as the "Carbon Cycle" because photosynthesis and cellular respiration involve the cycling of mostly oxygen, but not carbon, within living organisms such as plants and animals.

• The term "Carbon Cycle" is used because photosynthesis and cellular respiration occur exclusively in marine ecosystems, where carbon is the dominant element.

• This is referred to as the "Carbon Cycle" due to taking place primarily in carbon based soils.

• This is referred to as the "Carbon Cycle" because photosynthesis uses carbon (from carbon dioxide), and cellular respiration releases carbon (from carbon dioxide). In this way carbon is exchanged between animals and plants.

Since cows produce a large amount of methane (a greenhouse gas) due to microbes in their gut when cellular respiration is happening, what problem can this cause?

• An increase in greenhouse gasses could contribute to the planet getting too warm

• An increase in greenhouse gasses could cause the atmosphere to be too thick to breathe

• An increase in greenhouse gasses could contribute to the enlargement of Earth's orbit

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.

• Cellular respiration produces oxygen, while photosynthesis uses oxygen.

• Photosynthesis releases energy, while cellular respiration stores energy.

• Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O

• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy

• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

How can energy from the sun be transferred to animals?

• The sun's energy is transformed into food by plants, animals eat plants as food so that they can transform that food into energy.

• Plants produced energy through photosynthesis, animals that eat that energy can produce food.

• Plants transformed energy of the sun into gases that animals can breath in to use as energy through respiration.

• Animals are able to use energy from the sun by eating the plants that provides energy for the animals.
