Virtual Lab 5: Ecosystem simulator Read the Overview and launch this ecological system simulator. Familiarize yourself with the simulator interface. Notice that you can control which species are present in your environment initially and what the diets of each species are. The types of species in the program include Plants (A, B, C), Herbivores (A, B, C), Omnivores (A, B), and one Top Predator. You can set their diets by indicating what they feed on.

By setting up different initial configurations, you can investigate the evolution of this simulated ecological system.

The ecosystem simulator provides a dynamic and interactive platform to model ecological interactions among various species, including plants, herbivores, omnivores, and a top predator. Starting with a specific initial composition of species and their dietary preferences allows users to observe how populations change over time, revealing insights into ecological balance, competition, and coexistence.

When beginning with only two plant species, A and B, the simulation reveals that over time, plant A's population increases rapidly and reaches a maximum, while plant B diminishes to extinction. With continued simulation, the populations tend to reach an equilibrium, where the populations of A and B stabilize at comparable levels. This demonstrates competitive exclusion, where the more dominant plant species outcompetes the other under the given conditions. Conversely, when all three plant species (A, B, C) are present initially, the dynamics are different; typically, only the most competitive or adaptable species flourish while others are overshadowed and decline, resulting in a less diverse plant community over time unless conditions favor coexistence.

To create an ecosystem where all three plant species coexist, one must include herbivores and omnivores with diverse diets. For example, introducing Herbivore A that eats Plants A and C, Herbivore B that consumes Plants A and B, and Herbivore C that feeds on Plants B and C, fosters a balanced food web supporting biodiversity. Additional omnivores, such as Omnivore A that preys on Herbivores A and B, and Omnivore B that targets Herbivores B and C, further stabilize the system. The top predator, feeding on omnivores, maintains predator-prey balance and prevents overpopulation of lower trophic levels. Under these configurations, all three plant species, along with herbivores and omnivores, coexist sustainably, illustrating a complex but resilient ecosystem.

Achieving coexistence of all species depends on fine-tuning dietary relationships and population sizes. For instance, if plant C cannot persist despite multiple adjustments, it may indicate competitive disadvantages or insufficient predation pressure to balance the ecosystem. Systematic experimentation within the simulation (limiting the session to 90 minutes) reveals that diversity and stability hinge on intricate predator-prey relationships, resource distribution, and initial population densities.

This simulation reflects key principles in ecology, particularly biodiversity's role in resilience. Ecosystems with high diversity tend to be more robust, capable of withstanding environmental fluctuations, as different species buffer against disturbances. Conversely, simplified or imbalanced ecosystems are fragile, vulnerable to collapse if key species are lost or environmental conditions shift. The simulated model underscores that biodiversity preservation is crucial for ecological stability, and that ecosystems respond in complex ways to change, often attempting to adapt—but not always successfully.

In conclusion, the ecosystem simulator underscores the importance of species diversity, complex food web interactions, and adaptive balance for ecological stability. While the model simplifies real-world dynamics, it demonstrates that biodiversity generally enhances ecosystem robustness, supporting resilience against environmental disturbances. Managing and conserving biodiversity are therefore vital strategies in ecological stewardship and environmental sustainability efforts.
