Biodiversity Quiz

Why are humans considered the primary factor impacting biodiversity?

• Due to their consumption of resources

• Because of their contribution to climate change

• Through their destruction of habitats

• All of the above

How does adding earthworms to garden soil contribute to sustainability?

• By increasing nutrient cycling

• By decreasing soil erosion

• By promoting soil aeration

• By reducing water usage

Which of the following best describes the relationship between species diversity and ecosystem balance?

• Greater species diversity leads to increased competition

• Each species occupies a specific ecological niche

• More species result in less habitat space available

• Species diversity has no impact on ecosystem balance

How does a variety of species in an ecosystem contribute to its resilience?

• By increasing competition for resources

• By reducing the overall food supply

• By providing multiple ecological services

• By limiting the spread of diseases

Why does the variety of beaks among Darwin's finches confer an advantage?

• It allows for adaptation to different food sources

• It enables cooperation among finches

• It reduces inter-species competition

• It enhances reproductive success

How does biological diversity in an ecosystem impact the availability of food?

• It increases competition for limited resources

• It decreases food production due to overconsumption

• It promotes cooperation among species in food acquisition

• It has no effect on food supply

In what way do humans contribute to the decrease in biodiversity?

• By conserving natural habitats

• Through sustainable resource management

• By causing habitat destruction

• By promoting species reintroduction programs

How does introducing more plant varieties promote sustainability in gardening?

• By reducing soil nutrient depletion

• By increasing pollinator diversity

• By improving pest resistance

• By enhancing aesthetic appeal

What role does niche specialization play in maintaining ecosystem balance?

• It increases competition among species

• It ensures efficient resource utilization

• It leads to habitat fragmentation

• It reduces species diversity

How does a decrease in biodiversity impact ecosystem stability?

• It increases resilience to environmental changes

• It decreases the capacity for ecosystem recovery

• It promotes species adaptation

• It enhances ecosystem productivity
