1.)if the original amount of energy found in the producer trophic level is 100 kcal how much is passed on to the primary consumer trophic level? how does this amount limit the number of members in the next higher level?

2.)analyze what would happen to this ecosystem if one of the primary consumers was removed from the ecosystem? what would happen if a new tertiary consumer such as a mountain lion came into the ecosystem? describe how each level would be affected if each of these changes occurred.

1)
Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal. This means that the number of primary consumers can not be as high as that of the primary consumers due to the lower amount of energy they receive.

2)
If a producer is removed from an ecosystem, then there is less energy entering the ecosystem. The ecosystem would be not sustained properly.
If a tertiary consumer is introduced, it is likely to give competition to other higher level consumers. It will also decrease the number of secondary consumers, meaning their numbers will dwindle, which will cause the numbers of the tertiary consumers to remain low.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
