Answer:
In a forest succession, different groups of plants grow at a site over time.
Step-by-step explanation:
A forest succession has multiple stages to become successful.
Firstly - there is bare ground, like any other starting point.
After a time, there will be shrubs and small trees growing among the first plants, and shrubland develops.
Next, seedlings of tall forest trees germinate and grow in the shelter of the shrubs, and soon overtop them, forming a young forest.
And last but not least, in the mature forest, individual trees die and young saplings grow to replace them, but the forest’s composition and structure tend to remain the same for centuries.
