A Correct answer
Explanation

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and usually lacking soil, such as a lava flow or area left from retreated glacier is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.
