Because the lower levels of the food chain have the most energy so more organisms can be sustained, but as you go up the food chain, less and less energy is transferred so less organisms can survive
The answer Is B A new Species is forming
8. The cell wall<span> is the outer most covering of the </span>cell. ... The cell membrane<span> is present in almost all types of </span>cells<span>. The </span>cell wall<span> is present in bacteria, fungi, algae and plant </span>cell<span>.
9. </span><span>the spreading of something more widely.
10. </span><span>In </span>facilitated diffusion<span>, molecules only move with the aid of a protein in the membrane. In </span>simple diffusion<span>, molecules move down the concentration gradient but in </span>facilitated diffusion molecules move up the concentration gradient.
11. <span>a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one
12. </span>Differences<span>: </span>Passive Transport<span> (or Diffusion) moves ions from high concentration to low, using no metabolic energy. </span>Active Transport<span> moves ions from low concentration to high, using metabolic energy in the form of ATP. ... Both use ion channels to move ions across the cell membrane, in or out of the cell</span>
