if u remember the last question, first subquestion which had sumthin "Suggest three reasons why not all the energy in the wheat crop is available in animal feed" or sumthin like that i wrote:
1) not all the sunlight available to the wheat crop is used by it
2) animal may not eat all of the wheat crop , some of it is undigested
3) wheat crop may use some of its energy for respiration i.e. for growth or active transport
does that make sense?
overall i thot the questions had too many marks! all 3,4, 5 mark questions..loads of questions were overmarkd n were given like 4 or 5 marks..nyway for the table in the first question, i ticked "Scales/scaly skin" for birds, as all textbooks say birds have scales on their feet, but many ppl in my class sed u didnt hav 2 tick it!
