Couldnt have the original energy been created from those ocean bacteria organism things that make their own food without light? BAM VCAA!

I don't know if you were joking or not, but don't cyanobacteria photosynthesis?
According to wikipedia they comprise of 20-30% of the photosynthetic productivity on Earth... I is confuse. :(

I did temperature and light availability too, although I'm not sure if temperature is correct. My friend told me that in the description that it said the algae or whatever they were didn't have an optimal climate, but I figured that there would be a point where if the temperature was too great in the pond they would be killed. Do you reckon VCAA would accept this or nah?

It's small things like these that made the exam tricky. You really had to read the decription, something which I'm afraid I did not do too well :(

In the info it specified that the plant doesn't need consistent rainfall, particular climate etc.
So I said, keep toxic chemicals produced by the factory away from the plant, and keep animals away as they might use it as a food source, not sure if that was what they wanted lol

Hey what did you guys put for the calcium mc question? it had something about calcium being lower in the blood. I chose the one about absorbing calcium from intestines. But i wasn't sure...

I also picked the intestines one for the calcium MC

What did you guys put for the ethylene MC question?
I thought because it is lipid soluble then the receptors can't be on the cell membrane, but when stress (like the scratching of the plant surface) is imposed on a plant it produces more ethylene so the fruit ripens quicker? I think that was option B

Me too. I chose B because it said damage causes ethylene to be released
