If you ate a hamburger, you would probably only get about of the original energy from the sun.

If you ate a hamburger, you would probably only get about 1 % of the original energy from the sun.

First of all, we know that we only get 10% of energy during energy Transfer.

Sun  -  Grass    -  Cow   - Human
  
      100%           10 %      1 %      

hope this helps
