The answer would be D. Heterotrophs 
Explanation: 
Because A, B, C, and E are the producers, they make their own food and while D. are the consumers. They can’t make their own food so they must consume it.
        
             
        
        
        
Y - 4x ≤ -6y - 4x ≤ -6
We add 6y and 4x to each equality
7y ≤ 0 ≤ 6y + 4x -6
Observing:
7y ≤ 0, we see that the values of y can be only negative or 0, not positive.
So we are left with (-2,-14) (-1,-9) (0,-5)
We check the second equality:
6y + 4x - 6 ≥ 0 for these 3
None of the inequalities satisfy the given expressions simultaneously.
        
             
        
        
        
Answer:
Your using the word dreadful do describe a perfect world. You are also using perfect.
Explanation:
Dreadfully means two things, one is very badly. Like the performers played the instruments dreadfully. The other is Extremely. Which would make sense in you case. And for the reason that perfect stands out is because there is no such thing as a perfect world. We are always going to make mistakes no matter what.
