1. Set Initial Conditions:
2. • Initial Fish Population: Enter the starting number of fish in the provided box.
   • Food Availability (1 to 10): Set the availability of food on a scale of 1 to 10.
   • Number of Predators: Enter the number of predators in the ecosystem.
   • Pollution Level (1 to 10): Set the pollution level on a scale of 1 to 10.
   • Temperature (degrees Celsius): Enter the water temperature in degrees Celsius.

3. Run the Simulation:

   • Click the “Progress Time” button to advance the simulation and observe changes in the fish population.

4. Reset the Simulation:

   • Click the “Reset Simulation” button to start over with new initial conditions.

5. Observe and Analyze:

   • Monitor how changes in food availability, number of predators, pollution level, and temperature affect the fish population.

This interactive is a simplified simulation designed to help students learn and practice collecting and analyzing data. While there are many factors that affect fish populations in the real world, this simulation focuses on a few key variables to provide a clear and manageable learning experience.
