Below are sample questions representative of the exercises included on this worksheet and related 6.89 Model a Local Ecosystem skill assessments:

Problem 1Difficulty: Mastery
A neighborhood creek receives road salt in winter and lawn fertilizer in spring. Which model best explains year-round changes?
AA seasonal model including salt, nutrients, water chemistry, algae, sensitive insects, fish, and decomposers over time
BA model that lists the names of nearby roads but no organisms
CA model that treats every season as exactly the same
DA model with only one photograph of the creek in summer
Solution & Explanation:The strongest year-round model includes the changing inputs and the ecosystem responses across seasons.
Problem 2Difficulty: Mastery
A creek-side meadow model includes grasses, insects, frogs, snakes, hawks, rainfall, and mowing. Which revision best supports prediction when drought and a mowing change happen together?
ARemove rainfall because drought is not part of ecosystems
BUse one arrow from grass directly to hawk
CKeep only the hawks because top predators explain everything
DShow both lower plant growth from drought and reduced shelter from mowing, with effects moving through several food-web links
Solution & Explanation:The best model includes both changes and shows how they combine to affect the system.
Problem 3Difficulty: Mastery
A rain garden is installed to protect a school pond. Which model best shows how the rain garden can improve the pond ecosystem?
AA model that tracks playground noise levels
BA model with only flowers and no water movement
CA model showing water slowing, soaking in, and being filtered before reaching the pond
DA model showing fish building the rain garden by themselves
Solution & Explanation:The strongest model connects the rain garden's physical effects to better conditions in the pond.
