A.
Explanation:
Pioneer plants are to plants species that appear first in virgin land – such an after a volcanic eruption. They are mainly lower plants such as lichen, fungi, and noses. These species can grow on rocks and break them down over time to form soil. This is due to the fact that the plants have very shallow roots that can even grow in the small crevices of rocks and can draw water from the atmosphere – moisture. This releases the nutrients in the rocks and makes them available to higher plants that have deeper roots. The ecology of the region will ultimately be succeeded by a climax community over time, mainly dominated by tree species.
Answer:
Different materials have different densities. So it is False
In light reactions there is successful photosynthesis due to the fact one of the primary reactants for photosynthesis in the first place. At the end of the light reaction, there will be the normal photosynthesis products formed which are glucose and oxygen. For the dark reaction no products will be formed
Hiiiiiiiiiiiiiiiiiiiiiikiiiii
