Explanation:
Detailed explanation-1: -As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved.
Detailed explanation-2: -Energy flows straight through the ecosystem; it is lost as heat at each step, but it is never recycled. Matter is recycled and is not lost from the ecosystem.
