Biogeochemical Cycles

Front

What is the only process that removes carbon from the atmosphere?

Back

Photosynthesis is the process that removes carbon dioxide from the atmosphere by converting it into glucose using sunlight.

Front

Plant roots directly obtain water from?

Back

Plant roots directly obtain water from groundwater stored below the soil.

Front

Why do living things need nitrogen?

Back

Living things need nitrogen to make proteins and amino acids, which are essential for growth and repair.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process in which certain bacteria convert nitrogen gas from the atmosphere into ammonia, which can be used by plants.

Front

How do volcanoes affect carbon dioxide levels in the atmosphere?

Back

Geologic activity, such as volcanoes, increases the levels of CO2 in the atmosphere.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis plays a crucial role in the carbon cycle by absorbing carbon dioxide from the atmosphere and releasing oxygen.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, which can be accessed by plant roots.

Front

What are nitrates?

Back

Nitrates are compounds that contain nitrogen and oxygen, and they are essential nutrients for plants.

Front

What is the significance of decomposition in biogeochemical cycles?

Back

Decomposition breaks down dead organic matter, returning nutrients to the soil and making them available for new plant growth.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and infiltration.
