Below are sample questions representative of the exercises included on this worksheet and related 6.85 Biodiversity and Ecosystem Services skill assessments:

Problem 1Difficulty: Mastery

A restored meadow gains many plant species, but most are closely related grasses. A second meadow has fewer species but includes grasses, legumes, and flowering herbs. The second meadow supports more pollinators.

Which statement best explains why the second meadow supports more pollinators despite fewer species?

ALegumes reduce biodiversity because they add nitrogen.

BPhylogenetic and functional diversity can matter; a mix of functional groups (including flowering herbs) can better support pollinators than many similar grasses.

CPollinators prefer fewer plant types, so diversity reduces them.

DMore species always means more pollinators, regardless of traits.

Solution & Explanation:Remember: biodiversity is the variety of life (genes, species, and ecosystems). Ecosystem services are the benefits people get from ecosystem processes and organisms (provisioning, regulating, cultural, and supporting). Focus on what organisms do (their roles/traits), not just how many species there are; different roles can change how well an ecosystem provides a service. In the passage, the key detail points to phylogenetic and functional diversity can matter; a mix of functional groups (including flowering herbs) can better support pollinators than many similar grasses. That’s why choice B is best.

Problem 2Difficulty: Mastery

A scientist measures “ecosystem service value” only in dollars made from tourism. A second scientist measures services including water purification and carbon storage in biophysical units.

Which statement best explains why these approaches can lead to different conclusions?

AEcosystem services include many benefits not captured by market prices; valuing only tourism can miss regulating and supporting services that matter even without direct sales.

BDollar value is the only scientific way to measure ecosystem services.

CIf tourism is low, an ecosystem provides no services.

DBiophysical measures are cultural opinions and cannot be used.

Solution & Explanation:Remember: biodiversity is the variety of life (genes, species, and ecosystems). Ecosystem services are the benefits people get from ecosystem processes and organisms (provisioning, regulating, cultural, and supporting). Match the example to the correct service type: provisioning = goods (food, timber, medicines); regulating = natural control (floods, climate, water cleaning, pests); cultural = recreation/spiritual/education; supporting = underlying processes (nutrient cycling, soil formation). In the passage, the key detail points to ecosystem services include many benefits not captured by market prices; valuing only tourism can miss regulating and supporting services that matter even without direct sales. That’s why choice A is best.

Problem 3Difficulty: Mastery

A coastal community plants one salt-tolerant grass species on dunes. The dunes stabilize at first, but after a new fungal disease arrives, most grass dies and dunes erode.

Which statement best explains what this reveals about biodiversity and services?

AErosion protection is provisioning because it provides sand for construction.

BLow genetic or species diversity can make a system vulnerable to disease, risking the long-term stability of regulating services like erosion protection.

CUsing one species is always safest because it prevents competition.

DDisease proves biodiversity is higher because more organisms are present.

Solution & Explanation:Remember: biodiversity is the variety of life (genes, species, and ecosystems). Ecosystem services are the benefits people get from ecosystem processes and organisms (provisioning, regulating, cultural, and supporting). Match the example to the correct service type: provisioning = goods (food, timber, medicines); regulating = natural control (floods, climate, water cleaning, pests); cultural = recreation/spiritual/education; supporting = underlying processes (nutrient cycling, soil formation). In the passage, the key detail points to low genetic or species diversity can make a system vulnerable to disease, risking the long-term stability of regulating services like erosion protection. That’s why choice B is best.
