Biogeochemical Cycles Review

Front

What is the main reason matter can recycle through the biosphere?

Back

Biological systems do not use up matter; they transform it.

Front

What process takes Carbon Dioxide from the air and converts it into a form of carbon used by living things?

Back

Photosynthesis

Front

What is transpiration in the water cycle?

Back

Transpiration is the process where water is absorbed by plants and released as vapor into the atmosphere.

Front

Who primarily carries out nitrogen fixation?

Back

Bacteria.

Front

What cycle is primarily involved in the conversion of nitrogen into usable forms for plants?

Back

Nitrogen cycle.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis converts carbon dioxide into organic compounds, providing energy for living organisms.

Front

Define biogeochemical cycles.

Back

Biogeochemical cycles are the pathways by which chemical substances move through biotic (living) and abiotic (non-living) components of Earth.

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.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide as a byproduct.

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.
