The cell membrane functions as a selective barrier. We call these kind of membranes as differentially permeable or semi permeable membrane. It can decide what substances can pass in and out. Therefore it can surround the cytoplasm (which is the inside of a cell) to separate the cell's content from the surroundings.
Animals have many advantages. But plants can make food anywhere there is sunlight/ultraviolet rays. So no need to hunt unless you're a Venus Flytrap. So plant cells can sustain themselves easier to a degree. As with many things in biology, it all comes down the the circumstances.
Explanation:
The difference between first and second consumer are,
- <em>The</em><em> </em><em>first</em><em> </em><em>consumer</em><em> </em><em>are</em><em> </em><em>autot</em><em>r</em><em>op</em><em>h</em><em>ic</em><em> </em><em>in</em><em> </em><em>nature</em><em> </em><em>but</em><em> </em><em>second</em><em> </em><em>consumers</em><em> </em><em>are</em><em> </em><em>heterotrophic</em><em> </em><em>in</em><em> </em><em>nature</em><em>.</em>
- <em>The</em><em> </em><em>first</em><em> </em><em>consumer </em><em>are</em><em> </em><em>mostly</em><em> </em><em>plants</em><em> </em><em>and</em><em> </em><em>second</em><em> </em><em>consumer</em><em>s</em><em> </em><em>are</em><em> </em><em>mostly</em><em> </em><em>animals</em><em>.</em>
- <em>The</em><em> </em><em>first</em><em> </em><em>consumer are</em><em> </em><em>called</em><em> </em><em>producers</em><em> </em><em>and</em><em> </em><em>second</em><em> </em><em>consumer are</em><em> </em><em>called</em><em> </em><em>herbivores</em><em>. </em>

<span>The difference is where the material came from. Spoils come from overburden and is discarded as waste, whereas, tailings come from left over dredging of steam beds that are discarded as waste as well. </span>
