Ecological disturbance may be natural or man made.It is an event or force which cause for death of organisms or affecting the spatial distribution. Wind, drought, fire etc are exmples for this phenomenon

Answer 2

The statement “disturbance is by definition harmful and undesirable for the ecosystem.” is false.

Further explanation:

An ecosystem is the set of both the biotic as well as the abiotic components that interact with each other to sustain themselves. The ecosystem is made up of abiotic components like; sunlight, climate, water, minerals and soil. The biotic components of an ecosystem include plants, animals and microorganisms.

Any disturbance in the ecosystem can cause changes in either the biotic component or the abiotic components or both the components. The disturbances can be either natural or humanmade. The natural disturbances may include; drought, floods, volcanic eruptions and forest fires. The manmade disturbances may include; industrialization, urbanization and building up of dams.

It is not appropriate to say that all the disturbances in the ecosystem are harmful. This is because disturbances such as drought or floods can sometimes eradicate some of the harmful organisms that dwell in the ecosystem. Forest fires can also lead to the burning of such plants, which prohibited the growth of other plants or make the land barren.
