It is called speciation.
So it'll be D. Speciation
Hope this helped :)
Depending on the type of forest, they can.
<span>There are different types of mass movements. They are: 1. rockfall--free falling of rocks or debris of rocks from a steep cliff. 2. mudflow--commonly known as mud slides. This is another form of slope movement a proportion of clay and debris rapidly flow. 3.landslip/landslide--is a mass movement that involves a great range of ground movements. This can happen under water,at the coast or even on shore. 4. slump--happens along a curved surface over a short distance.5. soil creep--also known as downhill creep. This is a slow progression of rocks downward. Therefore, the answer to this question is "slump".</span>
Answer:
After a disturbance such as a fire or flood has occurred, an area can get reestablished by the process of secondary succession. Secondary succession can be described as an ecological succession in which life begins to form again in area which has been eradicated due to disturbances. Firstly, the pioneer species, such as small grasses or shrubs, will start to form on this land. Them with the passage of time the pioneer species will be replaced by the intermediate species such as different plants and trees. animals will start to occur more on this land. Finally, a complex community will arise to support life.
This is the excretory system
