Answer:
The ecosystem would collapse if producers were removed.
Explanation:
The primary consumers populating would decrease due to lack of food and if a species doesn’t have food they most likely won’t reproduce. The secondary consumers won’t have enough food either because their prey being the primary consumers would die off. All this leads to the down fall of ecosystem.
 
        
             
        
        
        
Out of the following given choices;
<span>A.     
</span>The mouse has a completely different DNA sequence
than the other mice. 
<span>B.     
</span> The
substituted nucleotide has the same directions as the original nucleotide. 
<span>C.     
</span>Substitutions in the nucleotides of a mouse's
DNA never affect their phenotypes.
<span>D.     
</span>DNA sequences don't determine the color of a
mouse's fur. 
The answer is B. Most probably, the nucleotide substitution did not translate to a change in the
amino acid sequence in the translated protein. As you may be aware, most amino
acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG.
Therefore, a substitution, that causes a change to either one of the sequences will not
change the amino acid.
