The secondary succession is triggered by a natural event (forest fires for example) that destroys an established ecosystem. The destroyed forest will then undergo a regrowth process. This secondary growth may look bizarrely different from the way how the original forest used to look like. There are several stages involved after the forest os being burned. The first stage involves the colonization of massively burned places by plants and fungi. The following stage starts when minuscule plants such as grasses dwell in the forest. And then, huge plants that require lots of direct sunlight will move in. Lastly, new trees will continuously grow up to a point where they makeup a forest that remains in time except there are major interventions.

Answer:
The five-and-five first aid action recommended by the red cross
Explanation:
When an infant is choking and becomes unresponsive, the five-and-five approach is recommended as a first aid treatment to dislodge the material blocking the airway.
<em>The five-and-five action involves alternation between giving the subject five back blows and five abdominal thrusts until the the choking material is dislodged or the subject becomes unconscious.</em>
If the infant becomes unconscious, CPR should be performed and further help should be sought.
Where is the picture? Is there a picture?
I think that genetic engineering is a good idea because it helps cure deseases that people cant cure, and could possibly cure cancer some day.
Hope my oppinion helped!
