Detailed explanation-1: -Primary succession happens when a new patch of land is created or exposed for the first time. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. During primary succession, organisms must start from scratch.
Detailed explanation-2: -In the ecological succession the biomass overall decreases. There are two main types of succession, primary and secondary. So the correct option is ‘Species diversity, biomass increases’.
Detailed explanation-3: -Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.
