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.

water evaporate
physical change is just change between solid/liquid/gas, other two are chemical changes
Chemical symbols are represented with their coefficients in a balanced reaction. Ethane and oxygen are the reactants, whereas carbon monoxide and water are the products.

<h3>What is Carbon monoxide?</h3>
Carbon monoxide, a colorless, incredibly lethal, odorless, tasteless, and flammable gas with the chemical formula CO, is a little less dense than air. Carbon monoxide is a compound made composed of one carbon atom and one oxygen atom joined by three bonds. This is the simplest molecule in the oxocarbon family. The term "carbonyl" refers to the carbon monoxide ligand in coordination complexes. It is an essential part of many industrial chemistry procedures.
Carbon monoxide plays important biological roles in all phylogenetic kingdoms.
