Why isn't respiration proportional to temperature of the surroundings?

Basically of got this graph that shows that as temperature increases, so does respiration, up to a point.

The data is

Temperature / Distance moved on respirometer

20c / 10mm
25c / 14mm
30c / 16mm
35c / 20mm
40c / 16mm

The questions asks whether or not the distance increases proprtionally to the temperature (no) but i also asks why not which is the bit i don't understand.

Basically why isn't respiration proportional to temperature?

So many people in Yahoo Answers make up new facets about God in order to keep up with new findings in science. I just read one answer where, in the big bang theory, the singularity is God's closed palm and the explosion was God's open palm. Whar are they going to say if the big bang theory is somehow proven wrong?

Should there be a denominator, or will (x-1)(x-2)(x-3) have been canceled out?

Florida government insists that warning sirens would have made little or no difference in the death toll of the February 2 tornadoes in the Central Florida area, which killed at least 20 people, because of tight building construction, and the sirens outdoor nature.

Furthermore the claim is made that since they do not exist the expense would not justify the means.

Considering that these were nocturnal tornadoes, do you think they are correct (that sirens would make no difference), or were the fatalities due to the fact that twisters occurred at night?

Also do you live in an area with outdoor warning sirens, and whether or not you do, do you think education would increase citizen purchase of weather radios?

My question is more of a poll. Not meant to incite any arguements. Do you Believe in God or do you lean more towards the Big Band Theory. I believe in God, but have always wondered about the big bang. Couldn't God have make the big bang happen.? Just wondered if everyone else was as curious about this as me. I have always wondered why scientist cant believe in both. Does this sound crazy to everyone?
