A farm plants native flower strips beside crops. More bee species visit, and fruit set increases. What ecosystem service is the farm getting from the added biodiversity?

A wetland with many plant and microbe species receives runoff. Nitrate levels downstream drop after water flows through it. What service is linked to that biodiversity?

A neighborhood replaces a paved lot with many native tree species. Nearby homes now need less air conditioning in summer. What ecosystem service is shown?

A restored oyster reef has oysters, crabs, and marsh grasses. During storms, waves behind the reef are much smaller than waves on open beaches nearby. What service does the biodiversity support?

A school garden has diverse fungi, bacteria, and worms. Dead leaves disappear, and vegetable plants grow better. What service is this ecosystem providing?

A school wants more butterflies, low water use, and no pesticides in its yard. Which design best meets all three criteria?

A town needs cleaner stream water, more wildlife habitat, and a low-cost plan. Which plan best meets all three criteria?

A berry farm needs more pollinators but can spare only a little land that is not planted with berries. Which design best fits these limits?

A coast town wants storm protection, nursery habitat for young fish, and low maintenance. Which design best meets all three goals?

A forest plan must lower the risk of severe wildfire while keeping old trees and wildlife habitat. Which design best meets these goals?

A park pond has algae blooms after fertilizer runoff. The goal is clearer water, amphibian habitat, and no added chemicals. What design best meets those constraints?

A highway cuts across an elk migration route. The goal is fewer elk deaths and an open migration route, without stopping traffic. Which design best fits?

An invasive plant is crowding a meadow. The goal is more native biodiversity without harming pollinators during bloom. What design best meets the constraints?

Plan A protects a large forest but stops some logging. Plan B allows most logging but protects small patches. If habitat protection matters most, what evaluation is strongest?

Plan A removes an old dam on a river. Plan B keeps the dam and its reservoir and stocks the river with hatchery fish. What trade-off is most accurate?

A farm compares a 30 m stream buffer of native plants with a 5 m buffer. What evaluation best compares the plans?

Plan A creates a no-fishing reserve on a reef. Plan B allows fishing except during spawning months. Fish recovery is the main goal. What evaluation is strongest?

A valley has too many deer eating young trees. Plan A reintroduces wolves. Plan B fences seedlings in small plots. What trade-off is most accurate?

A city roof can hold either native plants or solar panels. Which comparison of the two designs is strongest?

Plan A seeds a roadside with local native grasses and flowers. Plan B uses one fast-growing grass. Native mix costs more upfront. What trade-off is strongest?
