<u> Succession</u> refers to the process that facilitates plant communities gradually changing over a period of time in order to respond to their environment. 
Explanation:
Succession can be described as changes that occur in an ecosystem in response to the changes in the environment or any other disturbances. 
Succession can be of two types. 1. Primary succession 2.Secondary succession
Primary succession occurs on lands where there was no life before. With time, plants start to grow here and a community is developed.
Secondary succession occurs on lands that have been destroyed due to any disturbances like a flood or a fire. Over time, new plants start to grow on this land and a community is developed.

Answer and Explanation:
Both clouds and fog are closely related to precipitation. 
This can be explained first by the formation of clouds and fog, which begin when the air contains water vapor. This <u>water vapor is produced when there is an accumulation of moisture in the enviroment which leads to the formation of clouds. A similar process occurs with the formation of fog, which comes from saturation, that occurs after the evaporation and condensation processes that take place after precipitation (water cycle). </u>
Moreover, some types of clouds (cumulonimbus) are associated with precipitation as they could be accompanied by climatic phenomenon such as rain and snow.
