Biogeochemical Cycles

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of coal, natural gas, and oil. They are used as energy sources.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as vapor through pores in leaves.

Front

How is phosphorus released from rocks?

Back

Phosphorus is released from rocks through a process called weathering, which breaks down the rock and allows phosphorus to enter the soil.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria are crucial in the nitrogen cycle as they convert nitrogen gas from the atmosphere into forms that plants can use, such as ammonia and nitrates.

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, involving processes like photosynthesis and respiration.

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, and precipitation.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller particles through physical, chemical, or biological means, contributing to soil formation.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What is the role of decomposers in biogeochemical cycles?

Back

Decomposers, such as fungi and bacteria, break down dead organic matter, recycling nutrients back into the ecosystem and making them available for plants.

Front

What is the significance of the nitrogen cycle?

Back

The nitrogen cycle is essential for converting nitrogen into forms that living organisms can use, supporting plant growth and maintaining ecosystem health.
