Earth's ecosystem can be divided into 4 spheres, which are the atmosphere, the biosphere, the hydrosphere, and the geosphere. These spheres interact with each other and a change in one of them may cause a change in the other three spheres.
Within the ecosystem, the substances, such as water, carbon, oxygen, and nitrogen, undergo biochemical cycles. Through this cycle, the substances revolve through all spheres and are distributed throughout the whole ecosystem.
The statement is therefore TRUE.
