Answer:
Primary succession
Step-by-step explanation:
Primary succession, in the context of environmental sciences, refer to the evolution of an ecosystem over a certain period of time. For this condition to occur, sudden changes to the environment (such as described in the question) that are irreversible must have taken place. These changes would cause the current ecosystem to gradually go extinct – from its plants to its animals. With the new changes, a new ecosystem would take its place – species that could exist in the new ecosystem would procreate, perhaps even thrive more if the new environment is more suitable to them.
