Analyzing graphs!

anonymous · Answer

|dw:1423789515513:dw|The first graph in linear and the second graph is quadratic. The question related to these graphs is, are the invertebrates the same size. if not which is larger?

anonymous · Answer

I know that the invertebrates are not the same size. I just don't know how to answer which one is larger. The equations representing the graphs are y=Ac, where a is some constant, and y=Ac+KAc^2

The graphs show the relationship between Absorption and Concentration of oxygen.  Nothing else.  Is one a starfish and one a fruit-fly?  All we know is that they absorb oxygen at different rates with respect to concentration.

anonymous · Answer

Mhm, but the reason why they absorb oxygen at different rate is because of their size. lol

doc.brown · Answer

They could be the exact same size and absorb oxygen at different rates.

doc.brown · Answer

The bigger the insect (clams are invertebrates too) the higher the need for oxygen (so are worms).  Second graph.  $\frac{L^3}{L^2}$
