The **Pond Ecosystem Gizmo** is an interactive simulation that helps students understand the dynamics of a pond ecosystem, including how various organisms interact and depend on one another. It explores different components of the ecosystem, such as producers (plants), consumers (animals), and decomposers (bacteria and fungi), and how energy flows through the system. The Gizmo allows users to add or remove organisms, adjust environmental factors like temperature or light, and observe how these changes affect the balance of the ecosystem. The answer key typically provides guidance on questions related to how populations of organisms change over time, how energy is transferred, and how human activities might influence the pond's health. It is used as an educational tool to demonstrate concepts like biodiversity, food webs, and the importance of ecological balance.
