Based on the pyramid, which organism(s) provide the most available energy?

a) predator fish
b) birds and mammals
c) insects and zooplankton
d) phytoplankton and bacteria

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
