QUIZZES // Nutrient cycles and global ecosystems
Q1. Which one of the following is an important nutrient for plants?
Nitrogen
Lead
Carbon
Mendelevium
Q2. Which one of these is the best definition of the term ‘cycle’ in the phrase ‘nutrient cycle’?
A system with inputs and outputs
Events in the order in which they occur
A process that goes round and round
A series of organisms that eat each other
Q3. Which one of these returns nutrients to the soil in the nutrient cycle?
When the ground is saturated
When plants die or lose leaves
When an animal eats a plant or another animal
When farmers harvest crops from a field
Q4. The three stores in a nutrient cycle diagram are labelled S, B and L. What do these stand for?
Sodium, Bromine, Lithium
Surface, Bedrock, Lifeforms
Soil, Biomass, Litter
Sub-aerial, Biome, Littoral
Q5. Which one of these transfers in the nutrient cycle diagram is where bacteria release nutrients from dead plants and animals back into the soil?
Weathering
Leaching
Decomposition
Littering
Q6. Which one of these transfers can bring nutrients into an ecosystem?
Plant uptake
Surface run-off
Leaching
Weathering
Q7. Which one of these is the abbreviation used for littering in a nutrient cycle diagram?
Li
Le
L
LG
Q8. Nutrient cycle diagrams that show differences between ecosystems are called:
Gurlzmell diagrams
Gersmehl diagrams
Gerstner cycles
Gesundheit cycles
Q9. Which one of these is a feature of a tropical rainforest nutrient cycle diagram?
Litter is the biggest store
Soil is the biggest store
Biomass is the biggest store
All the stores are equal in size
Q10. Which one of these is a feature of a desert nutrient cycle diagram?
Litter is the biggest store
Soil is the biggest store
Biomass is the biggest store
All the stores are equal in size
Q11. Which one of these is a feature of a taiga nutrient cycle diagram?
Litter is the biggest store
Soil is the biggest store
Biomass is the biggest store
All the stores are equal in size
Q12. Which one of these explains why nutrients cycle so quickly in the tropical rainforest ecosystem?
Warm, wet conditions mean that decomposition is rapid and so is plant growth
Heavy rainfall leaches nutrients from the soil or out of the litter layer in surface run-off
There is very little rain so nutrients are not lost through runoff or leaching
Decomposition happens slowly because so much litter is produced
Q13. Which one of these is a reason for why tropical rainforest soils are low in nutrients?
Low plant uptake
Rapid decomposition
Massive biomass
Small soil store
Q14. Which one of the following explains why most nutrients in desert ecosystems remain in the soil?
Few plants can survive in the hot, dry conditions so not much litter is produced
There is very little rain, so there is little run-off or leaching
The dry conditions mean that decomposition is slow
Weathering of the bedrock happens slowly in the very dry conditions
Q15. In the presentation, what two factors are on the axes of the graph of different ecosystem nutrient cycles?
Temperature (y axis) and precipitation (x axis)
Nutrients (y axis) and time (x axis)
Longitude (y axis) and latitude (x axis)
Stores (y axis) and transfers (x axis)
