Because there is only a finite amount of energy. Energy is lost between each trophic stage. The top predator would gain the least amount of energy, shared between the least amount of organisms within the predator species. Typically there just aren't any other animals that can kill and eat the top predator, but there also wouldn't be enough of the top predator to eat so any species above them would quickly die out.
Answer:
Cell membranes are essentially lipid-based so they're hydrophobic. Therefore, most hydrophobic molecules can pass through the cell membrane
Explanation:
Hope this helps :)
At the interface of two fluids, there is a difference in pressure. This leads to the existence of a surface force, the surface tension, that shapes the fluid.
The surface tension of water is roughly 72 dynes/cm,
However, that is highly dependant on the characteristics of the considered material (physical and chemical), and thus all fluids (and thus liquids) do not have the same surface tension.
What did one cell say to his sister cell that stepped on his toe?
Mitosis!
The answer is C because metabolism is part of how we stay alive ourselves.
