Respuesta :
Initial conditions and chance play roles in the process of succession so if the ecosystem is in a good condition and chance is on it's side (no natural disasters or human interventions occur), succession can't happen because there is no destroyed area to build new upon.
As long as the ecosystem inputs remain the same, the ecosystem will remain stable. Only when there is a fire, drought, or other disturbance in the ecosystem, will the ecosystem change. A new set of plants will arise to most efficiently use the resources that are available under the new conditions. However, over time, if the disturbance is temporary, the ecosystem will eventually revert to the stable ecosystem that was there before the disturbance.
What is a stable ecosystem?
Stability (of an ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.
What is succession?
Ecological succession is the process of change in the species structure of an ecological community over time.
Causes of succession:
- Topographical: Extreme conditions cause abiotic topographical factors, which are mainly involved with secondary succession. Landslides and mudslides are examples of this type of factor.
- Soil: The soil, an abiotic factor, of an environment affects ecological primary succession greatly. Different species of plants require different soil conditions.
- Climate: Climate, an abiotic factor highly involved in both primary and secondary succession, plays a significant role in determining the direction of succession in an environment.
Ecosystem remains stable:
- It’s all about balance, left to its own devises nature constantly rebalances.
- populations increase and decrease all the time, usually due to food sources either being plentiful or scarce, when plentiful the animals that feed on them thrive and breed.
- when scarce they starve and decline in number, this decline in numbers allows time for the food source to regrow or reproduce (if the food source is another animal species),
- The ecosystem is unaffected in the long run and remains in balance.
Thus, it can be concluded that As long as the ecosystem inputs remain the same, the ecosystem will remain stable.
