**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.
