Carbon Cycle

Front

What process involves plants taking in carbon dioxide to produce glucose?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What releases carbon dioxide into the atmosphere when animals breathe out?

Back

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

Front

Which process describes the breakdown of organic matter by bacteria and fungi?

Back

Decomposition is the process where bacteria and fungi break down dead organic matter, returning nutrients to the soil.

Front

What organisms in the ocean absorb the most carbon dioxide?

Back

Algae and marine plants are the primary organisms that absorb carbon dioxide from the ocean.

Front

True or False: Animals decomposing into the ground increases the amount of carbon in the soil.

Back

True. When animals decompose, their bodies release carbon into the soil, enriching it.

Front

What is the carbon cycle?

Back

The carbon cycle is the process through 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 during photosynthesis, helping to reduce atmospheric carbon levels.

Front

What is a carbon sink?

Back

A carbon sink is a natural reservoir that stores carbon-containing chemical compounds for an indefinite period, such as forests and oceans.

Front

How does combustion affect the carbon cycle?

Back

Combustion releases carbon dioxide into the atmosphere, contributing to greenhouse gas emissions.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.
