Which of the following correctly compares the changes that take place in an ecosystem during primary succession and secondary succession? A] Primary succession takes place over a long period of time in an area that has been disrupted by a natural disaster, while secondary succession occurs quickly on newly formed land.

B] Primary succession takes place over a long period of time on newly formed land, while secondary succession occurs quickly in areas that have disrupted by a natural disaster.

C] Primary succession takes place quickly on newly formed land, while secondary succession occurs over a long period of time in an area that has been disrupted by a natural disaster.

D] Primary succession takes place quickly in an area that has been disrupted by a natural disaster, while secondary succession occurs over a long period of time on newly formed land.

Primary succession takes place over a long period of time in an area that has been disrupted by a natural disaster, while secondary succession occurs quickly on newly formed land. Primary succession takes place over a long period of time on newly formed land, while secondary succession occurs quickly in areas that have disrupted by a natural disaster. Primary succession takes place quickly on newly formed land, while secondary succession occurs over a long period of time in an area that has been disrupted by a natural disaster. Primary succession takes place quickly in an area that has been disrupted by a natural disaster, while secondary succession occurs over a long period of time on newly formed land. Primary succession occurs on newly formed land such as a volcano. No organic content and organisms are present at the beginning. It is a relatively slow process.

Secondary succession occurs on previously occupied land such as an area that has been devastated by a forest fire. Soil with organic content is found on this piece of land and organisms may be present at the beginning. This process is faster than primary succession.
