The following distribution of offspring was observed:
blue wings, green eyes 1,070
blue wings, black eyes 177
red wings, green eyes 180
red wings, black eyes 1,072
in a particular species of mammal, blue wings (b) are dominant to red wings (b), and green eyes (g) are dominant to black eyes (g). based on these data, what is the recombination frequency? (see book section: module 9.18)
a. 86%
b. 7
c. 17%
d. 14%

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.    

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

actually the answer is c
