Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, and decomposition.

What is respiration in animals?

Back

Respiration is the process by which animals take in oxygen and release carbon dioxide.

Front

What do plants produce during photosynthesis?

Back

Plants produce oxygen and glucose during photosynthesis.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic matter, releasing oxygen as a byproduct.

Front

What happens when humans burn fossil fuels?

Back

When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.

Front

What is the significance of tree farms in the carbon cycle?

Back

Tree farms help remove carbon dioxide from the atmosphere, contributing to carbon sequestration.

Front

What process does NOT produce carbon dioxide?

Back

Photosynthesis does not produce carbon dioxide; it consumes it.

Front

What is the main gas used by animals during respiration?

Back

Oxygen is the main gas used by animals during respiration.

Front

What is the main gas produced by animals during respiration?

Back

Carbon dioxide is the main gas produced by animals during respiration.

Front

How do plants contribute to the carbon cycle?

Back

Plants contribute to the carbon cycle by absorbing carbon dioxide during photosynthesis and releasing oxygen.
