If this were to be a true and or false statement, then most bacteria found in soil may be harmful to us, yet to the plants and other organisms that rely on those plants, these bacteria are extremely helpful as they facilitate the recycling of essential nutrients and other ions that plants require such as nitrogen, which ultimately allows traces of nitrogen to be taken in by other consumers within a food chain, a crucial component for growth and development.

As , when the earthworms crawl inside the soil , it gets holes by which air can enter the soil and the growth of plant is fast.
        
             
        
        
        
I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:
You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled
If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
See my picture for the Punnett Squares for both answers!
