Stability in Ecosystems: All ecosystems are stable systems. This means that they maintain a natural balance. An ecosystem involves the flows of nutrients and energy (in the form of food). However, a balance is maintained between the availability and use of nutrients by recycling them through natural processes. A balance is also required to provide different amounts of energy (from food) needed by different organisms. For example, in a forest ecosystem, the numbers of the prey (like rabbits) are always more than the numbers of the predator (like foxes), to ensure adequate food for the predator.
