Describe the relationship between chromosomes, messenger rna, and proteins.

A chromosome is a packaged and organized structure containing most of the DNA of a living organism.  Messenger RNA  is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.  Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
