Question

what order do the changes in the succession of an ecosystem occur? Rearrange the boxes so that the first change to occur is on the left and the last change to occur is on the right.

Answer 1

The changes in the succession of an ecosystem occur in the following order: primary succession, secondary succession, and sequential appearance and disappearance of species.

Step-by-step explanation:

The changes in the succession of an ecosystem occur in a specific order. The order of changes in succession is as follows:

1. Primary succession: This occurs on newly formed or exposed rock. Pioneer species, such as lichens and some plants, colonize the area and break down the rock to form soil.
2. Secondary succession: This occurs when a part of an existing ecosystem is disturbed, but remnants of the previous community remain. Once again, pioneer species colonize the area and facilitate the growth of other species.
3. Sequential appearance and disappearance of species: Over time, the community undergoes changes as different groups of species grow and are replaced by other groups. This leads to a more or less permanent community.
