Because liquids and solids are denser than gasses.
Explanation:
Solids and liquids are denser than gasses making it easier for things like sound to conduct through them. Being dense contributes to a better conduction because the particles and such within the solid or liquid are closer together which allows for things like sound to travel at a much faster rate because they're so much easier to vibrate.
As you go up in an ecosystem the bigger animals have less energy. While the organisms down at the bottom like plants that create their own energy have greater amounts.
