Flashcards on Biogeochemical cycles
Click on the flashcard to see the answer
What are biogeochemical cycles?
Natural processes that recycle elements and compounds through living organisms and the environment.
Name the four main biogeochemical cycles.
Carbon cycle, nitrogen cycle, phosphorus cycle, and water cycle.
What is the carbon cycle?
The process by which carbon is cycled between the atmosphere, plants, animals, and the Earth.
Describe the nitrogen cycle.
The process by which nitrogen is converted into various forms and circulated between living organisms and the environment.
What is the role of phosphorus in biogeochemical cycles?
Phosphorus is an essential nutrient for living organisms and is cycled through the environment.
Explain the water cycle.
The continuous movement of water on, above, and below the surface of the Earth.
How do biogeochemical cycles affect ecosystems?
They ensure the availability of essential nutrients, regulate nutrient cycles, and support the balance of ecosystems.
What happens during the process of photosynthesis in the carbon cycle?
Plants convert carbon dioxide and sunlight into glucose and oxygen.
What causes the release of phosphorus from rocks in the phosphorus cycle?
Weathering and erosion.
How does human activity impact biogeochemical cycles?
Activities like deforestation, burning fossil fuels, and excessive use of fertilizers disrupt the natural balance of these cycles.
Why is the water cycle important for life on Earth?
It ensures the availability of water for all living organisms and helps regulate Earth's climate.
What are some factors that influence the rate of nutrient cycling in ecosystems?
Temperature, precipitation, soil conditions, and the presence of decomposers.
Which biogeochemical cycle is associated with the growth of harmful algal blooms in water bodies?
Phosphorus cycle.
In which cycle is bacteria involved in converting nitrogen gas into a usable form for plants?
Nitrogen cycle.
What is the primary source of carbon dioxide in the atmosphere?
Burning of fossil fuels and deforestation.
