Carbohydrates, they break down easily
Hibernation is when animals that do not survive in the winter go to sleep for the whole season. Before those animals go to sleep, they store a whole bunch of food and water and they live their lives in their dreams. Bears are one animal that hibernate and they store berries. In google definition, "(of an animal or plant) spend the winter in a dormant state".
I hope this helped and I hope you understand.
By recording the explosions, they can quickly figure out what happened if a bombing incident occurred.By recording everything that happened during and after the explosion, they can find evidence and solve a case quicker.
The population size should decrease at higher trophic levels. The reason is there isn't enough prey to feed the predators as the trophic levels increase. For example, the biggest impact in the ocean would be if you lost all the small fish in an ocean because the predators would be left with less food. It's not exactly correlating, but if you think a little about the statistics it makes sense.
hope this helps
