Coyote black-footed ferret
hawk
bison
rabbit
prairie dog
blue stem grass
Which argument for protecting the prairie dog best relates to the flow of energy in the ecosystem?
A. Prairie dogs eat grass and other plants that cattle graze on
B. Prairie dogs are an important source of food for many other species.
C Prairie dogs dig in the soil, which improves its quality and helps plants grow.
D. Prairie dogs make burrows which are used as habitat by other important species.

I think that would be B:  Prairie dogs are an important source of food for many other species.

hope this helps. and please correct me if I'm wrong ^^

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
