Algal blooms can result in creating low oxygen zones, referred to as the dead zones in aquatic ecosystems.

This leaves the ecosystem depleted of oxygen and aggravate the living conditions in the ecosystems,
She is able to determine it to be a mollusk because it has an internal shell.
Most of the changes in an ecosystem are gradual. The gradual changes taking place in the ecosystem allows the organisms to evolve slowly. As a result of evolution, the species can adapt and survive in the changing environment.
