Carbon is essential for the survival, growth and reproduction of living things. It is a finite resource that comes in different forms and transfers from living to non-living things in various ways. Carbon stays balanced with other chemical reactions in the air and bodies of water through the carbon cycle.
Why is carbon so important in biological molecules? 1) Carbon has very high melting point and sublimation point. This gives it advantage over other elements that are common in biological molecules such as H, N or O. 2) In additâ¦ion, it can form multiple strong covalent bonds with other atoms (N, H, O, C).
