Question

Why would a lava flow from a volcano result in primary succession instead of secondary succession? Because the water has dried O Because the animals have died O Because the plants have died O Because the ecosystem is starting on rock instead of soil​

Answer 1

Answer: Because the ecosystem is starting on rock instead of soil​

Explanation: because rock, rather than soil, is where the ecosystem begins. Primary succession happens in places with no soil, including those that have just had a volcanic eruption where the lava has obliterated all flora and topsoil. Lichens and mosses colonize bare rock surfaces in the early phases of primary succession, gradually eroding the rock and producing soil for other plants to grow in. Contrarily, secondary succession involves the regrowth of vegetation from the leftover plants and seeds in the soil and takes place in locations where the soil has already been established, such as after a forest fire.
