Biogeochemical Cycles

Front

What is the process by which carbon dioxide leaves the atmosphere?

Back

Photosynthesis is the process by which carbon dioxide is absorbed by plants to produce oxygen and glucose.

Front

What is precipitation in the context of the water cycle?

Back

Precipitation refers to the process of water droplets or ice crystals falling from the sky, including rain, snow, sleet, and hail.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms.

Front

Which process does not produce carbon dioxide?

Back

Photosynthesis does not produce carbon dioxide; instead, it consumes it.

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.

Front

Define biogeochemical cycles.

Back

Biogeochemical cycles are natural processes that recycle nutrients in various chemical forms from the environment to organisms and back to the environment.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric CO2 levels.

Front

What is transpiration?

Back

Transpiration is the process by which water vapor is released from plants into the atmosphere through small openings in leaves called stomata.

Front

Explain the water cycle.

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What is runoff in the water cycle?

Back

Runoff is the flow of water, usually from precipitation, that moves across the ground and returns to bodies of water.
