Choose two ecosystems, a marine and a terrestrial ecosystem. Create biomass and energy pyramids for each ecosystem. Then, study and
compare each pyramid in terms of production efficiency and productivity
Focus on the following points when working on this activity
1. The difference between the pyramids in each ecosystem.
2. The efficiency with which energy is transferred through all the trophic levels in the Energy and Biomass pyramids.
3. Explain how each level is a biomass to the next level in both pyramids.
Use the following keywords when researching: primary productivity, efficiency, production, blomass pyramids, and productivity pyramids.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
