Students are asked to predict what would happen to the algae in a pond if fertilizer from a field was washed into the pond. They are also asked to explain why they think the fertilizer would have the predicted effect.This constructed response item is a sample of test items prepared and used in past National Assessment of Education Progress (NAEP) administrations.

| Benchmarks (3 - 5) |
|
| C. | Compare changes in an organism's ecosystem/habitat that affect its survival. |
|
| Grade Level Indicators (Grade 3) |
|
| 6. | Describe how changes in an organism's habitat are sometimes beneficial and sometimes harmful. |
|
| Grade Level Indicators (Grade 5) |
|
| 4. | Summarize that organisms can survive only in ecosystems in which their needs can be met (e.g., food, water, shelter, air, carrying capacity and waste disposal). The world has different ecosystems and distinct ecosystems support the lives of different types of organisms. |
| 6. | Analyze how all organisms, including humans, cause changes in their ecosystems and how these changes can be beneficial, neutral or detrimental (e.g., beaver ponds, earthworm burrows, grasshoppers eating plants, people planting and cutting trees, and people introducing a new species). |

| The characteristics of organisms (Grades Kindergarten - 4) |
|
| Organisms have basic needs. For example, animals need air, water, and food; plants require air, water, nutrients, and light. Organisms can survive only in environments in which their needs can be met. The world has many different environments, and distinct environments support the life of different types of organisms. |
