Describe the conservation of mass in a food web?

The conservation of mass in a food web refers to the principle that matter is neither created nor destroyed within the ecosystem. Instead, energy and nutrients are transferred through various trophic levels as organisms consume one another. For instance, when a plant is eaten by an herbivore, the mass of the plant is converted into the mass of the herbivore, while also releasing energy through metabolic processes. Ultimately, this cycle continues, maintaining a balance of mass within the ecosystem.
