Dead animals and plants are not abiotic and they are now providing food for fungi and bacteria. Without the abiotic factors, it would be difficult for the biotic to survive.

Nucleic acids are molecules that are essential to, and characteristic of, life on Earth. There are two basic types of nucleic acid, DNA (oligonucleotide acid) and RNA (nucleic acid). This exercise will focus on DNA, although ways in which it differs from RNA will also be presented. DNA is found in all organisms from the smallest bacteria to humans. DNA has the same composition and structure in all organisms!DNA has two important functions.1 - it is the genetic material that is passed from one generation to the next.2 - it is the coded information that tells cells how to make proteins.
