👉 A percolator is a type of biological model used to describe how species pass through a network of water channels. In this model, the walls of the channels are filled with small holes and the water molecules move between them, allowing for the exchange of substances like nutrients, gases, and waste material. Percolators can be found in various environments such as soil, air, and water. They are important because they allow species to pass through these networks efficiently while also maintaining a balance of nutrients and
