[quote=\"Helping--Hand\"]Hmm... For the pond community question I put (1). I was guessing that the butterflies are part of the pond community, together with other flying insects like damselfly, dragonfly etc. I also thought that frogs ate butterflies... do they?

I dont understand... why is it 6 organisms? I thought there is 8? Explain Please :thankyou:

Actually, I thought the qn ask populations?

Caterpillars and butterflies=1 population
tadpoles and frogs= 1 population
fishes=1 population
plants (don't know what types)= 3 populations
Total=6 populations
:)[/quote]I think i was too stressed... I was perplexed and wrote another question..... Booo Hoooo I really feel like crying out my lungs... :stompfeet: :siam: :siam:[/quote]

Don't be too stress! Cool down. What is done cannot be undone. Don't think about it anymore! Relax and concentrate on your revision for HMT (if you have). If not, start playing!!

Hi, what did your children write for the OE question about the water passing through the box of sand and into a glass, '' Person A says that the water was clean for drinking, do you agree? Why?\"

Hi,
I wrote: No. The water might contain harmful bacteria that cannot be seen through the naked eye. (not sure but something like that).

May I ask anyone here? If I have DSA and got shortlisted, how many marks above must we get to get into the school?

:thankyou:
