B-amount of matter remains relatively constant in an ecosystem. This concept is based on the Law of Conservation of Mass, which states that matter cannot be created or destroyed in an isolated system. In the context of an ecosystem, matter is recycled through biogeochemical cycles, such as the water cycle, carbon cycle, nitrogen cycle, and others. These cycles allow matter to change forms and move through different parts of the ecosystem – from the air to the soil, into organisms, and back out into the environment – but the total amount of matter remains constant.
