When something is in equilibrium, it's in balance. In the real world of ecosystems, nothing is ever perfectly balanced. So an ecosystem in equilibrium is said to be in a relatively stable state. This means that the populations of various animals in the ecosystem are generally staying within a similar range. Biodiversity is the variety of life forms in an ecosystem. An ecosystem that is rich in biodiversity stabilizes the net productivity and makes the ecosystem more resistant to exotic species. It maintains the ecosystem by maintaining the food chain.

Increasing species diversity can influence ecosystem functions such as productivity by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community. When something is in equilibrium, it's in balance. In the real world of ecosystems, nothing is ever perfectly balanced. So an ecosystem in equilibrium is said to be in a relatively stable state. This means that the populations of various animals in the ecosystem are generally staying within a similar range.Ecological balance has been defined by various online dictionaries as "a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession." and "A stable balance in the numbers of each species. In ecology, an ecosystem is said to possess ecological stability if it is capable of returning to its equilibrium state after a perturbation or does not experience unexpected large changes in its characteristics across time. The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem's ability to remain stable when confronted with a disturbance. Resilience is the speed at which an ecosystem recovers from a disturbance. Ecosystems are organized in a state of balance where species coexist with other species. If something happens in an ecosystem, it can shift from a state of balance to a state of imbalance. Ecological imbalance is when a natural or human-caused disturbance disrupts the natural balance of an ecosystem. Ecosystem stability a community is generally considered stable when the abundance of species stays relatively constant and unstable when the abundance has strong fluctuations. 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). If the organisms Having in an ecosystem use up nutrients, like nitrogen, from their environment, without replenishing them, soon the system will collapse.
