if we compare the genetic codes of the four organisms seen here, which statement is most accurate?

a. all four organisms have exactly the same genetic code.

b. all four organisms have the same genome, but the number of chromosomes per organism varies.

c. all four organisms have exactly the same components in their dna, but it varies in number and sequence.

d. there are almost no similarities between the genetic code of these four organisms, and are placed into four different kingdoms.

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.    

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b
