It asks about the type of variation which is controlled by more than one gene. So we know two types of variation- Discrete and Continuous. Discrete is controlled by a single gene whereas Continuous is controlled by more than one gene hence it is known polygenic inheritance.
So I had chosen Polygenic (silly me didn't read the question!) *facepalm*
I think I have to edit the marking scheme and upload the right answers to some questions :smile:

Hope that is clear now

Omg nooo I forgot to add arrows - did not see that question at all. I legit double checked and I just didn’t see the question, ugh I hope that mark doesn’t make a difference between an A and a B

for the pyramid one would it not be the irregular one with a small bottom tier. i’m sure a whole bush would have enough energy to feed lots of caterpillars. if the producer was grass let’s say then yes it would be regular but not an entire bush.

No only trees have enough energy to sustain - only when trees r involved it’s irregular

That was my logic too, I put down A for that one
