Question

what is the fundamental difference in how energy and matter move through an ecosystem? energy flows in one direction, while matter is cycled and reused. matter flows in one direction, while energy is cycled and reused. both energy and matter are cycled and reused within the ecosystem. both energy and matter enter the ecosystem and are then destroyed.

Explanation:

In an ecosystem, energy flows in one direction (e.g., from the sun to producers to consumers), while matter (such as elements like carbon, nitrogen) is cycled and reused (e.g., through biogeochemical cycles like the carbon cycle, nitrogen cycle).

Answer:

Energy flows in one direction, while matter is cycled and reused.
