A scientist finds a new organism that may be either a bird or a bat, but it is not clear which group it belongs to. He is pretty sure that the organism has analogous structures with bats and homologous structures with birds, as suggested by genomic data. The organism has one trait that is shared with bats but not birds. Which group should he choose for the new organism and why? A) Bats because of the analogous structures; the trait shared only with bats is ancestral.
B) Birds because of the homologous structures; the trait shared only with bats is ancestral.
C) Birds because of the homologous structures; the trait shared only with bats is derived.

answer; ///i believe the answer is (antioxidant);

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.
