    An ecological disturbance can be define as long term or temporary change in the biotic and abiotic factors of the ecosystem. Not every ecological disturbance is bad or disasterous.

    For example, the low intensity forest fire is a temporary disturbance. It may kill some plant species and animal species, but at the same time it may be beneficial for fire adapted species which dependents upon fire as a an important ecological factor responsible for breaking up the seeds, pods and cones so as to facilitate the spread of seeds. These seeds will germinate in suitable condition and give birth to new plants. Such a plant species will in near future can stabilize the ecosystem.

    As explained below

    Explanation:

    The ecosystem is a system of systems that are affected due to the process of ecological services on the planet earth. It is a community of living organisms that reacts to themselves and thus there interaction is a cause and effect of the earth's external and internal dynamism. The ecosystem has various process the are seen in energy flow and primary production of organic matter along with the nutrient cycle functioning. Thus at certain levels, various process acting in the ecosystem tends to disturb its natural flow and hence which in turn leads to ecological imbalance and these imbalances are cleared from the ecosystem by the ecosystem itself. As it has been seen that forest fires and other disturbance that is deliberately caused into the environment can impact it to a certain level and if the organism does not tolerate this disturbance its can be fatal for the ecosystem also. Some disturbances badly damage or impact the ecosystem to a greater extent than it takes time other changes bring a positive impact on the ecological surroundings. Certain damages impact productivity while other disturbances are needed to bring about a change in the biological diversity of systems such as an invasion of species.
