Pyramids of biomass can be represented on a suitable scale. It takes into account the size of the organisms aswell unlike pyramids of number.

What are the advantages of using a pyramid of biomass/measuring in biomass???

measuring biomass is more reliabe than just counting organisms at each level

Thanks, but that's like saying 'I hope there's no Biology!' :biggrin:

Awkward HSW questions are inevitable in an AQA Biology exam..especially in Unit 4!

Also...nice uni firm choice..... :tongue:

Also, according to CGP, increases crop yield as more CO2 - limiting factor in photosynthesis and may disrupt insect life cycles, they may emerge from larval stage quicker.

yep the larval thing comes from increased temperatures. for every 1 degree they may come out 10 days earlier than expected. forgot about the crop yields thingy so cheers!

how you gonna approach the paper btw? I think im gonna do the last two questions first. get the 5 markers out the way whilst im fresh and tackle the supposedly hardest question... what you think?

good luck bro!

I'm afraid you're right, what I should have said was "I hope there's no awkward ones :biggrin:

"

Thanks, you also going to Warwick?

Yep, Law though.... I don't think I could take anymore of Biology :tongue:

Lovely campus, have you picked accomodation? I've put Cryfield and Whitefield down as top two, only because they're the cheapest and I'm a cheapskate :biggrin:

So I'm not completely off-topic: Good luck if you're sitting this :smile:

Yeah I might do that, they're usually just simple recall, no thinking required.

I always run out of time, I don't i've ever sat a Bio paper yet where I've had time to check my answers, so going to try my best to leave some checking time, I have a tendency to make really stupid mistakes.... like missing questions.... :tongue:

Good luck to you too :smile:
