The goal of a conclusion is to state whether the hypothesis was supported by the data
Explanation:
A conclusion is a type of small paragraph where we explain the overall outcome of an experimental procedure and after it mention the proposed hypothesis at the starting of the experiment was correct or not.
These discussions which is mentioned in the conclusion is helpful for further experiments or also test that could be done to support your findings in the present experiment. This part could also be called perspectives.

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:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.
