Building on the feedback loop, this phase focuses on the two different scenerios of the pneumatophore system: the 'before' or normal scenerio and the 'after' or high tide / coastal flooding scenerio of the mangrove and how it affects the pneumatophores. As the water sweeps in, some of the pneumatophores get submerged under water while others continue to provide the supply of oxygen and nutrients to the root network and trees, which would not have been possible without the pneumatophores. Local organisms, such as, crabs and worms, take shelter in and around the pneumatophores.
According to the given formula in the diagram, it has been proven that the higher the density of pneumatophores in a given area, the more oxygenated the soil condition will be, which in turn reduces the toxic build-up of chemicals in the soil.
