Organisms from the higher trophic levels consume organisms from the lower trophic level. In this process, energy is lost as metabolic heat. Thus, primary producers, such as sedge, contain the greatest amount of energy originally from the sunlight. The next trophic level belongs to primary consumers, such as arctic hare, that consume primary producers resulting in less energy. Similarly, arctic fox eats arctic hare, and energy is lost again. The highest trophic level is tertiary consumers such as wolf, therefore, the wolf contains the least amount of energy.

Answer:
What happens during DNA replication?
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
