(D) Abiotic factors are non-living components of the environment. $1$. Water,nutrients,and oxygen are essential for the germination of seeds and the early stages of plant growth. $2$. Light is not strictly required for the initial germination or early growth of many plants,as they can utilize stored food reserves in the seed. $3$. However,once the plant exhausts its stored reserves,it must perform photosynthesis to continue growing,which requires light. Therefore,sustained growth is dependent on the presence of light.

Which abiotic factor is not essential for the early growth of a plant,but growth is sustained only in its presence?
