What statement holds true for the amount of matter in a successful food web?

In a successful food web, the amount of matter is conserved, meaning that matter is neither created nor destroyed but is transformed and cycled through different organisms and ecosystems. Energy flows through the food web as organisms consume one another, but the overall mass of matter remains constant. This cycling of nutrients supports biodiversity and the stability of ecosystems, allowing for the continuous growth and reproduction of organisms. Thus, a healthy food web relies on effective nutrient cycling to sustain life.
