When one thing dies, or is taken away from the food web, then this could happen:
Let's say plants are taken away. Then, herbivores have nothing to eat, sot hey die. Then, carnivores have nothing to eat, and the same thing happens, etc.
Plants are the base of survival for every organism in nearly every ecosystem.
Energy and matter characterize both physical and biological systems. These systems are defined both by the types of energy and matter they contain and by how that matter and energy move through and between systems. ... This means that energy and matter can change forms but cannot be created or destroyed.
