Answer:
in order to restore a damage ecosystem, to sow native seeds or transplanting individual plants is a first step towards the solution.
2. Because it is difficult to study biogeochemical cycles globally, it is important to research in a smaller scale in order to measure the ecosystem processes.
Explanation:
The true statement is - B. The rock cycle is powered by the movement of tectonic plates.
Almost all rocks on our planet came to existence because of the tectonic activity. The movement of the tectonic plates is enabling the magma from the mantle layer to come to the surface, cool off, and create new layers of rocks. On the other hand, the same process, where there's subdustion zones, is moving the existing rocks down into the mantle layer where they are ''recycled'' in way, and this process is continuing to happen all the time.
