What This Document Is
This document is a student exploration activity focused on prairie ecosystems, designed for a Molecular Biology course (BP 723) at Harvard University. It utilizes a Gizmo (interactive simulation) to investigate the relationships between organisms – grass, prairie dogs, ferrets, and foxes – within a prairie environment. The activity explores concepts like producers, consumers, herbivores, carnivores, populations, equilibrium, and food chains.
Why This Document Matters
This exploration is intended for Harvard University students enrolled in Molecular Biology (BP 723). It serves as a practical exercise to reinforce understanding of ecological principles and how populations interact within a defined ecosystem. It’s likely used as part of a larger unit on ecosystems, population dynamics, or biological interactions. Students will use this to apply theoretical knowledge to a simulated environment.
Common Limitations or Challenges
This document is a guided exploration, not a comprehensive textbook chapter. It focuses specifically on a prairie ecosystem and a limited set of organisms. It doesn’t cover the complexities of all ecosystems or delve deeply into the molecular mechanisms underlying biological interactions. The Gizmo provides a simplified model; real-world ecosystems are far more intricate.
What This Document Provides
The full document includes:
* Prior Knowledge Questions to assess initial understanding.
* A “Gizmo Warm-up” section to familiarize students with the simulation interface.
* Three Activities (A, B, and C) with guided questions and experimental prompts.
* Investigations into the role of grass as a producer.
* Exercises in constructing and analyzing food chains.
* Exploration of long-term changes and the impact of endangered species (black-footed ferrets).
* Data analysis using bar graphs and line graphs within the Gizmo.
This preview only provides a summary of the document’s structure and content. It does *not* include the Gizmo simulation itself, the answers to the questions, or the results of the experiments.
