Mississippi Sound and Bight Food Web Challenge

Build populations from the bottom up, then see which populations can feed — and which become food.

Population rule: Environmental stress is applied first, then feeding and predation occur. Producers can supply up to 2 grazing units per population, but stressful salinity or temperature can reduce survival. Surviving populations carry forward to the next measured year.

Build one starting food web, then change salinity and temperature and rerun the same web to compare outcomes. See what happens when the Mississippi Sound becomes fresh! What happens when the Mississippi Sound warms up?

Start with the base of the web. Add phytoplankton, seagrass, and small consumers before attempting many predators.

Strategy: Add enough producers and small consumers before adding larger predators.
