<u>Answer:</u>
The correct answer for this is: Microevolution.
<u>Explanation:</u>
The change of England's Biston betularia moth populations from light colored to dark colored is an example of 'Microevolution'.
Basically, the change that occurs over time in the allele frequencies within a group of species or population is known as microevolution.
The four processes due to which this change occurs include gene flow, selection (natural and artificial), mutation and genetic drift.

Answer:
fire
landslide
avalanche
Explanation:
Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.
On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.
