Use this tool to model what happens to the populations of a seagrass ecosystem over time when one component of the ecosystem is increased or decreased. Record both your ideas and the results you observe.
Objective
Students construct and explore hypotheses about population dynamics in a seagrass environment.
Students model and analyse relationships between organisms in a seagrass environment.
Students compare their hypothesis to data about population dynamics in a seagrass environment.
