Biogeochemical Cycles (Nutrient Cycles)

Front

Where is carbon stored in the environment?

Back

Carbon is stored in various places including fossil fuels, wood of trees, and calcium carbonate (shells and bones).

Front

What converts nitrogen into a usable form for plants and animals?

Back

Bacteria convert nitrogen into a usable form for plants and animals.

Front

How is carbon dioxide added to the atmosphere?

Back

Carbon dioxide is added to the atmosphere through burning fossil fuels, cellular respiration, and decomposing organic matter.

Front

What are the gases that trap heat in the Earth's atmosphere causing global warming?

Back

These gases are known as Green House gases.

Front

What is the largest reservoir for nitrogen?

Back

The largest reservoir for nitrogen is the atmosphere.

Front

What is the role of decomposers in nutrient cycles?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for plants.

Front

What is photosynthesis and its role in the carbon cycle?

Back

Photosynthesis is the process by which plants convert carbon dioxide and sunlight into glucose and oxygen, playing a crucial role in the carbon cycle.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including fixation, nitrification, and denitrification.

Front

What is the significance of the phosphorus cycle?

Back

The phosphorus cycle is important for the growth of plants and animals, as phosphorus is a key component of DNA, RNA, and ATP.

Front

How do human activities impact biogeochemical cycles?

Back

Human activities such as deforestation, pollution, and the use of fertilizers can disrupt natural biogeochemical cycles.
