Biogeochemical Cycles

Front

What is a biogeochemical cycle?

Back

A biogeochemical cycle is the movement of elements and compounds through living organisms and the physical environment, involving biological, geological, and chemical processes.

What are the main components of the water cycle?

Back

The main components of the water cycle include evaporation, condensation, precipitation, and infiltration.

Front

How do fossils form?

Back

Fossils form when ancient biomass is converted to fossil fuels through time, heat, and pressure.

Front

What is the role of adhesion in the water cycle?

Back

Adhesion allows water to stick to particles of dust in the air, facilitating the condensation process that forms clouds.

Front

What organisms are primarily responsible for fossil formation?

Back

Plants and animals are primarily responsible for fossil formation.

Front

What is evaporation?

Back

Evaporation is the process by which water turns into a gas, typically due to heat.

Front

What process does NOT produce carbon dioxide?

Back

Photosynthesis does NOT produce carbon dioxide; it consumes it.

Front

What is the difference between cohesion and adhesion?

Back

Cohesion is the attraction between molecules of the same substance, while adhesion is the attraction between molecules of different substances.

Front

What is the significance of carbon cycles in ecosystems?

Back

Carbon cycles are crucial for regulating the Earth's climate and supporting life by recycling carbon through photosynthesis, respiration, and decomposition.

Front

What is the role of decomposers in biogeochemical cycles?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and facilitating nutrient cycling.
