Which of the following statements is false? a. disturbance in an ecosystem is an event that changes the availability of resources in that ecosystem. b. disturbance are by definition harmful and undesirable for ecosystem. c. disturbance can be natural or man-made. d. disturbance can cause changes in the organisms in an ecosystem

B

Explanation:

Not all disturbances to an ecosystem are harmful. Most natural disturbances, such as fires, floods, and volcanoes are actually useful. They mitigate the dominance of a few species in an ecosystem and therefore increase biodiversity. For example, fire destroys the canopy of a forest and gives a chance to shorter shadow-intolerant trees at the forest floor to flourish. These plant also supports a wide range of higher organisms hence increasing the biodiversity of a forest. Volcano also revitalizes the ecosystem by bringing in new minerals and making the ground fertile for secondary succession.
