In an ecosystem, energy is captured from the sun or in some rare cases, heat from the interior of Earth by producers. Energy is transferred to higher levels of
the ecosystem as food. At each level, much of the energy is lost as heat to the
environment so it is not available to the next trophic level. The amount of food
energy available to the top consumers is much less than the amount produced in
the ecosystem. According to this passage the energy lost between trophic levels

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
