The Carbon Cycle

Front

What is the process that gets carbon from the atmosphere to plants called?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide (CO2) from the atmosphere into glucose and oxygen.

Front

What is the process that gets carbon from plants to animals called?

Back

Consumption (eating) is the process where animals obtain carbon by eating plants or other animals.

Front

What do bacteria release back into the atmosphere when they decompose dead plants?

Back

Bacteria release carbon back into the atmosphere during the decomposition of dead plants.

Front

True or False: Through the process of photosynthesis, plants pull CO2 from the air to make plant food for themselves.

Back

True. Plants use CO2 from the air in photosynthesis to create food.

Front

What do ocean coral and oysters use carbon to create?

Back

Ocean coral and oysters use carbon to create shells.

Front

Define the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle by consuming plants and other animals, and by exhaling carbon dioxide during respiration.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.

Front

What is the significance of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus maintaining the carbon cycle.
