Answer:
secondary succession
Explanation:
In the described scenario we have a destruction of an ecosystem because of natural causes, volcano in this case. All that has left after the volcanic eruption has been barren land. After this has happened life started colonizing the volcanic island again, in a process known as primary succession. In the primary succession it is the organisms that have the lowest of requirements for survival that will inhabit the island. Over time, as they die, they will provide biomass for the ground, thus soil will start to form. Once there's soil formed a process called secondary succession will start. In this process the island will start to be inhabited by some plants and smaller animals. These plants and animals will contribute to further enhancing the living conditions on the island, and the island will gradually be getting larger plants and larger animals, thus a new ecosystem will be formed on the place of the old one.

<h3>What is a Hydrosphere?</h3>
This refers to the total amount of water on a planet and includes water that is on the surface of the planet, underground, and in the air.
Hence, we can see that some of the components of a hydrosphere are liquid and frozen surface waters, groundwater held in soil and rock, and atmospheric water vapor.
Therefore, Some examples of a hydrosphere are:
- Seas – the Black Sea, Caspian Sea, Persian Gulf, Adriatic Sea, Mediterranean Sea, and the Red Sea.
- Glaciers,
- Lakes.
- Rivers.
- Streams.
- Clouds.
