What is the carbon cycle?
The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment.
True or False: Carbon is only found in the atmosphere.
False
Fill in the blank: Carbon dioxide is absorbed by plants during ______.
photosynthesis
What process do animals use to release carbon dioxide?
Respiration
Which of the following is a major reservoir of carbon? A) Atmosphere B) Oceans C) Fossil Fuels D) All of the above
D) All of the above
What role do decomposers play in the carbon cycle?
Decomposers break down dead organic matter, releasing carbon back into the atmosphere and soil.
True or False: The carbon cycle is a closed system.
True
What is the primary human activity that impacts the carbon cycle?
Burning fossil fuels
Fill in the blank: The process of converting organic matter into fossil fuels is called ______.
carbon sequestration
What is the greenhouse effect related to the carbon cycle?
The greenhouse effect occurs when carbon dioxide and other greenhouse gases trap heat in the atmosphere.
Which process releases carbon stored in rocks?
Weathering
True or False: Oceans act as a carbon sink.
True
What is the significance of phytoplankton in the carbon cycle?
Phytoplankton perform photosynthesis and absorb carbon dioxide from the ocean.
What is the term for the long-term storage of carbon?
Carbon sequestration
Fill in the blank: Carbon is transferred from the atmosphere to living organisms through ______.
photosynthesis
What is the role of soil in the carbon cycle?
Soil stores carbon in the form of organic matter and releases it through decomposition.
True or False: Deforestation increases the amount of carbon dioxide in the atmosphere.
True
What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gases emitted by an individual, event, or organization.
Which gas is primarily responsible for climate change due to its abundance in the carbon cycle?
Carbon dioxide
What are fossil fuels primarily made of?
Carbon
Fill in the blank: The process of converting carbon dioxide into organic compounds by plants is known as ______.
photosynthesis
What is the impact of ocean acidification on the carbon cycle?
Ocean acidification reduces the ocean’s ability to absorb carbon dioxide.
How do volcanic eruptions affect the carbon cycle?
Volcanic eruptions release carbon dioxide into the atmosphere.
True or False: Carbon can be found in all living organisms.
True
