What is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen?
Fermentation
Decomposition
Photosynthesis
Respiration
What is the main source of atmospheric carbon dioxide?
Industrial waste
Volcanic eruptions
Ocean currents
Burning of fossil fuels and deforestation
How does deforestation impact the carbon cycle?
It only impacts the carbon cycle in the oceans
It decreases atmospheric carbon levels
It increases atmospheric carbon levels
It has no impact on atmospheric carbon levels
What is the role of decomposers in the carbon cycle?
Release carbon back into the atmosphere as carbon dioxide
Convert carbon into oxygen
Store carbon in the soil
Absorb carbon from the atmosphere
What is the equation for photosynthesis?
carbon dioxide + glucose → water + oxygen
carbon dioxide + water → oxygen + glucose
glucose + oxygen → carbon dioxide + water
water + oxygen → glucose + carbon dioxide
How does burning fossil fuels contribute to the increase in atmospheric carbon dioxide?
Burning fossil fuels absorbs carbon dioxide from the atmosphere.
Burning fossil fuels has no impact on atmospheric carbon dioxide levels.
Burning fossil fuels reduces the amount of carbon dioxide in the atmosphere.
Burning fossil fuels releases carbon dioxide into the atmosphere.
What are the products of respiration?
Oxygen and glucose
Carbon monoxide, and methane
Carbon dioxide and water

How do human activities such as industrialization and transportation affect the carbon cycle?
They increase the amount of carbon dioxide in the atmosphere
They decrease the amount of carbon dioxide in the atmosphere
They only affect the nitrogen cycle
They have no impact on the carbon cycle
What is the role of the ocean in the carbon cycle?
Causing an increase in methane production
Releasing carbon dioxide into the atmosphere
Having no impact on the carbon cycle
