What is an example of a natural disturbance to an ecosystem?
Natural disturbances are one way an ecosystem can become unbalanced. As the name implies, natural disturbances have natural causes, such as weather, geological forces, or biological changes. Fires and floods are examples of natural disturbances that force change upon an ecosystem. Natural disturbances also be caused by diseases, severe storms, insects, volcanic activity, earthquakes, droughts, and long-term freezing.But natural disturbances are also beneficial in some cases. There are even some ecosystems that have adapted to become dependent on natural disturbances to maintain their balance. For example, longleaf pine forests depend on fire to control undergrowth in the forest. Without a forest fire clearing the way for new seedlings to grow, the tiny new trees are unable to compete with the thick brush and die.
Why do scientists think they know more about science than politicians? Gore wouldn't LIE!?
