In this task, students are asked to engage in a three-part process: first, develop a model that helps them describe the relationships between parts of an ecosystem in Australia (part 1), then consider what happens when rabbits are introduced to this ecosystem (part 2), and finally consider the role of decomposers in the system. The task scaffolds students through showing their understanding of ecosystem dynamics, providing them with opportunities to practice and demonstrate aspects of the three dimensions. The publicly available task was developed as part of the Stanford NGSS Assessment Project (SNAP) and can be found here.
