If there was a sudden drop in temperature after the evolution of the first living cells, predict how that might have affected the changes in the atmosphere and the evolution of cyanobacteria and other autotrophs. Explain your answer.

Well assuming that there is still sunlight (not really sure how drastic the drop in temperature might be) it would most likely make it too cold for cyanobacteria and other autotrophs to grow. 
The consequences of this would be that they would not be able to do photosynthesis. Now if you think about what photosynthesis produces you should be able to figure out why it might be bad for other living organisms.

how is anaerobic respiration affected by changes in temperature?

raspberryjam · Answer

Okay well I'm pretty sure colder temperatures isn't very effective for anaerobic respiration but temperatures that are too hot can be bad as well since it can start denaturing important proteins.
