<span>The most ancient of all animal lineages.</span>
The organism that is a primary consumer in this question is A - Caterpillar
If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around. They are not strong enough to hold organs or hold its shape.

False.
Explanation:
Blood is one of the most important connective tissue that helps in the transportation of molecules. Blood contains the red blood cells, white blood cell, platelets and plasma,
The different blood type are A, B, AB and O. The universal recipient is blood group AB and can accepts the blood of all the different blood types. They have both the antigen A and B and no antigen. Blood is not the universal recipient but the blood type AB is universal recipient.
Thus, the answer is false.
