The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.
<h3>Trophic Level</h3>
The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.
More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding. 
In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.

Answer:
Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. That causes their genes to become more common in the population over time, and it's the way species evolve to adapt to changes in their environment.
