Final Test Review

Which of the following is NOT necessary for photosynthesis to occur in plants?

• Light energy

• Water

• Soil

• CO2

A green plant is kept in a brightly lighted area for 48 hours. What will most likely occur if the light intensity is then decreased during the next 48 hours?

• Photosynthesis will stop completely.

• The rate at which nitrogen is used by the plant will increase.

• The rate at which oxygen is released from the plant will decrease.

• Glucose production inside each plant cell will increase.

Which factor can limit the rate of photosynthesis in plants?

• Temperature

• Oxygen concentration

• Glucose production

• Soil pH

What conclusion can you make about photosynthesis based on the following graph?

• More oxygen is required for photosynthesis when the color of light is closer to blue and red.

• More oxygen is produced during photosynthesis when the color of light is closer to blue and red.

• More oxygen is required for photosynthesis when the color of light is closer to green.

• More oxygen is produced during photosynthesis when the color of light is closer to green.

Which of the following is false regarding forests?

• Forests act as carbon sinks, meaning more carbon is taken in by photosynthesis than given off by respiration and decomposition.

• Deforestation (the cutting down of trees) would decrease the amount of atmospheric carbon because forests release carbon dioxide through respiration.

• Forests should be protected, as we rely on them to reduce the effects of climate change.

• Deforestation (the cutting down of trees) would increase the amount of atmospheric carbon because forests take in carbon dioxide through photosynthesis.

Which of the following is necessary for fermentation to occur in organisms?

• Glucose

• Oxygen

• Soil

• CO2

Which best explains why biofuels are considered more "climate-friendly" than fossil fuels?

• Biofuels do not release any carbon dioxide.

• Biofuels store carbon dioxide permanently.

• Biofuels recycle recently captured carbon dioxide.

• Biofuels produce more energy than fossil fuels.

What can we do to reduce the amount of carbon dioxide in the atmosphere?

• Take the stairs when possible.

• Unplug electronics when not in use.

• Switch to LED light bulbs.

• Take shorter showers.

• All of the above.

Which of the following is a likely consequence of warmer sand temperatures at sea turtle nesting sites?

• Increased hatching success due to faster incubation times.

• Production of mostly female hatchlings, disrupting population balance.

• Greater protection from predators during nesting season.

• Altering the sex ratio of hatchlings, producing more male turtles.

Which of the following best describes the environmental impact of fast fashion on climate change?

• Fast fashion decreases carbon emissions due to efficient manufacturing processes.

• Fast fashion has a neutral effect on climate change since it promotes recycling of clothing.

• Fast fashion accelerates climate change by increasing greenhouse gas emissions throughout its lifecycle.

• Fast fashion contributes to climate change mitigation through its use of sustainable fabrics and ethical labor practices.
