An enhancer is a region in the DNA containing about 50-1500 base pairs that can be bound to proteins to increase the likelihood of transcription of a certain gene.
In the cell, the enhancer functions are limited by the formation of loops that hold specific genes and enhancers in close proximity.
By doing so there will be structural distortion of the DNA which is important for limiting enhancer functions.
The picture given displays an ecosystem's food chain. The animals are the organisms that the energy flows through and the arrows represent where the enerrgy is going.
Question: Which obtains more energy, the rabbit or the fox?
