SCIENCE

You job as an environmental scientist is to study the impact the park has on the pond ecosystem. The pond contains trout and catfish. Catfish are very tolerant of pollution, but trout are much more sensitive and die off easily when exposed to excessive pollutants. Before the land and pond were disturbed by the construction of the playground, hiking trail, and parking lot, you counted the number of fish in the pond. At that time, Cypress Pond contained 100 trout and 100 catfish. Now you need to design an experiment to monitor the park’s impact on the populations of trout and catfish over the next 12 months. 1. What is the purpose of your experiment?
