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>

Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
Answer:
B
Explanation:
Radiometric dating uses naturally occurring radioactive elements such as carbon-14 within the rock or fossil to estimate its approximate age. The half-life of the element must also be known. The amount of the radioactive trace element is compared to, in a ratio, with that of the number of the decay product elements. This approximate age can then be relatively compared to those of other rocks or fossils.
