Hello! Please help me with this question!! I'm desperate and have the AP test this week. A letter answer and short explanation would be so so helpful!

Answer 1

energy of producers = 25470

energy of primary consumers = 3821

now: percentage of energy tranferred to primary consumers = 3821/25470*100 = 15.00196% or 15% in round figure

energy of secondary consumers = 573

% of energy transferred to secondary consumers = 537/3821*100 = 14.99% or 15% in round figure

energy of tertiary consumers = 86

% of energy transferred to tertiary consumers = 86/573*100 = 15.0087% or 15% in round figure

so the answer is 15
