During the experiment, i only took a 9ml sample from the tank containing the fish and tank containing 7.3 grams of worms. So i took a 9ml sample from the fish tank of 6000ml and 9ml sample from the worm tank of 200ml

Lets say the results are exactly like you expect. What concepts would you talk about? What im looking for is some topic of discussion concerning my results, regardless of the values are perfectly right.

that is a good parameter.

keep the quantities low. as worms will eat less
it isn't what you do that matters but it is how you do it

the ammonia and urea come from the excretory system, assuming there's a significant difference, why would this be the case? your answer should relate to their evolutionary history.
