Biogeochemical Cycles

Front

What is the water cycle?

Back

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

Front

What is transpiration?

Back

Transpiration is the process by which plants lose water vapor through small openings in their leaves called stomata.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria decompose dead organic matter, releasing nitrogen back into the atmosphere and soil, making it available for plants.

Front

Which cycle does NOT include an atmospheric component?

Back

The phosphorus cycle does not have an atmospheric component; it primarily involves soil, water, and living organisms.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen, effectively removing carbon from the atmosphere.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from clouds to the Earth's surface.

Front

What is the carbon cycle?

Back

The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment, including photosynthesis, respiration, and decomposition.

Front

What is the role of producers in biogeochemical cycles?

Back

Producers, such as plants, convert inorganic substances into organic matter through photosynthesis, forming the base of the food chain.
