Biogeochemical Cycles

Front

What is the process of water droplets or ice crystals falling from the sky?

Back

Precipitation is the process of water droplets or ice crystals falling from the sky, which includes rain, snow, sleet, and hail.

Front

What do organisms use nitrogen to form?

Back

Organisms use nitrogen to form proteins and nucleic acids, which are essential for growth and development.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including fixation, nitrification, and denitrification.

Front

How does carbon dioxide leave the atmosphere?

Back

Carbon dioxide leaves the atmosphere primarily through photosynthesis, where plants convert CO2 into glucose and oxygen.

Front

What converts atmospheric nitrogen into a usable form for plants?

Back

Bacteria convert atmospheric nitrogen into a usable form for plants through a process called nitrogen fixation.

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 like evaporation, condensation, and precipitation.

Front

Define evaporation in the context of the water cycle.

Back

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

Front

What role do decomposers play in biogeochemical cycles?

Back

Decomposers break down dead organisms, returning nutrients to the soil and making them available for plants.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

Explain the term 'biogeochemical cycle'.

Back

A biogeochemical cycle is the movement of elements and compounds through living organisms and the physical environment.
