Answer:
plants
animals
Explanation:
From the given choices only plants and animals are biotic in nature. Biotic factors are factors that can be attributed to living organisms.
The other choices such as water, light and minerals are abiotic. They are do not originate from living organisms.
Both biotic and abiotic factors are present within the ecosystem. In fact, they influence the ecosystem to a very large extent.
Together, these factors shapes the ecosystem.
The dehydration product of
oh in the presence of acid is Propene.
<h3>
Explain Propene and write its Chemical and Molecular formula?</h3>
Like ethene, propene (sometimes referred to as propylene) is a crucial building element for a variety of compounds, including the common polymer, poly (propene). But unlike ethene, propene is easily converted by substitution reactions into a variety of significant compounds. Propene is a colourless gas with a little aroma of petroleum.
Propene is an organic compound that belongs to the alkene family. It is a hydrocarbon with two carbon atoms and four hydrogen atoms. Propene's molecular structure is
.
Propene is a hydrocarbon with the chemical formula
. It is a gas at room temperature and pressure, but condenses to a liquid when pressurised or cooled.

According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.
Here NaOH is a base as it can donate OH-.
As NaOH is a strong base it will have very high dissociation constant.
Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.
![NaOH --> Na^{+}(aq) + OH^{-}(aq)](https://tex.z-dn.net/?f=NaOH%20%20--%3E%20Na%5E%7B%2B%7D%28aq%29%20%20%2B%20OH%5E%7B-%7D%28aq%29)
Thus in a solution of NaOH we will expect the following two ions
