Cellulose is composed of 44.44% of carbon atom, 6.17% hydrogen atom, and 49.39% oxygen atom. The chemical formula of cellulose is (C6H10O5)n.
The correct answer would be through adaptation and eventually over time they had to evolve to the area around them which made them develop over time to have longer necks .
