Which of the following best describes the changes that take place in an ecosystem during primary succession?

Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees.

Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire.

Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species.

Natural disasters cause many populations to migrate to a new location in order to survive.

Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees sounds like the answer. Primary succession is the type that happens when a land that previously HAS NOT supported plant life slowly begins to form and ecosystem. Secondary succession, like choice two, happens when a place that has had plant life before but a natural disaster got rid of the plants.
