Biogeochemical Cycles starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Biogeochemical Cycles.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
Describe the process of denitrification and its significance in the nitrogen cycle.
Describe the process of transpiration in the water cycle.
Describe the role of lightning in the nitrogen cycle.
Explain how deforestation can affect the carbon cycle.
Explain how human activities can lead to eutrophication in aquatic ecosystems.
Explain the importance of biogeochemical cycles for life on Earth.
Explain the role of decomposers in the biogeochemical cycles.
Explain why phosphorus is considered a limiting nutrient in many ecosystems.
Explain why the cycling of nutrients is essential for ecosystem sustainability.
A factory releases large amounts of nitrogen oxides into the atmosphere. Describe the potential impact this could have on both terrestrial and aquatic ecosystems.
A region experiences a prolonged drought, drastically reducing the amount of water available for plant uptake. Explain how this could impact the cycling of carbon and nitrogen in the ecosystem.
Describe the process of biological magnification and explain how it relates to biogeochemical cycles.
Explain how the sulfur cycle connects the atmosphere, lithosphere, and biosphere, and describe one way human activities have altered this cycle.
Explain why the cycling of sulfur is important for the formation of proteins in living organisms.
