BIOLOGY HELP, please!! I have my exam in a mere week and I'm not sure of the answer..I have past papers but no mark schemes. #pointless
also, if anyone could help;
Why is nitrate uptake faster in well oxygenated (aerated) soils?
Suggest why a blood worm can tolerate high pollution levels?
Name one organic compound found in a plant? and name a type of decomposer which helps break down starch?
Any of the answers at all would be fantastic, THANK YOU

Is this a question where a 'blurb' is given? If you read and understand it then you might be better of figuring the answer yourself. I would suggest you read the question again and review The Nitrogen Cycle.

From the question it seems you have to know some components of soil flora and fauna. With the 'suggest' questions I'm sure they would have given you a clue in the question - maybe the have adapted to something? They have a mechanism to tolerate high pollution - read the stem of the question.

Organic compound in plant should be easy - revise photosynthesis.

Decomposer - what do you think?

Think about aerobic and anaerobic conditions and which produces the better yield of ATP
In addition in anaerobic conditions there is an increas of dentriyfing bacteria...(fiigure out from here)
And think about nitrogen cycle ... if anaerbobic what would be the problem.. think of decombosers and saprobiotic microorganisms
