D) repeatedly back and forth through living and nonliving parts of the ecosystem

Explanation:

Matter is contained in both living and non-living components of the Earth. An atom is the smallest indivisible component of every matter. This means that matter is made up of atoms.

In an ecosystem, organisms feed on one another in order to survive. However, as they do this, matter is transferred from one organism to another. This transfer of matter (atoms) occurs repeatedly repeatedly back and forth in a cyclical manner through living and nonliving parts of the ecosystem.
