Carbon Cycle Flashcard 1 Z

Front

What is the carbon cycle?

Back

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

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert organic matter into energy, releasing carbon dioxide back into the atmosphere.

Front

Where is the majority of Earth's carbon stored?

Back

The majority of Earth's carbon is stored in the ocean, followed by the geosphere (rocks and soil), atmosphere, and biosphere (living organisms).

Front

What is the geosphere/lithosphere?

Back

The geosphere, also known as the lithosphere, includes all the land and rock on Earth, including mountains, soil, and ocean floors.

Front

What is the hydrosphere?

Back

The hydrosphere encompasses all the water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where living organisms interact with each other and their environment.

Front

What is carbon dioxide?

Back

Carbon dioxide (CO2) is a colorless gas that is a natural component of Earth's atmosphere, produced by respiration and combustion, and used by plants during photosynthesis.

Front

What is ammonium?

Back

Ammonium (NH4+) is a positively charged ion that does not contain carbon atoms and is often found in fertilizers.

Front

What are fossil fuels?

Back

Fossil fuels, such as coal, petroleum, and natural gas, are carbon-rich energy sources formed from the remains of ancient plants and animals.
