Step-by- step Explanation:
- Since the percentge is gradually decreasing a point will come when it will be Zero. Therefore number of trophic level is limited and typically less than 10.
- If we properly look at the pattern 100%>10%>1%>0.1%. We observe that, only ten percent of available energy is transferred from one trophic level to the next.
- Now, if we look at the structure of the model, The box representing the primary consumer is larger than the boxes representing other consumers Thus, we can conclude that, Among the consumers in the ecosystem, first level consumer have the most available energy.
Thus , sclaims B,C and D supported by the model.
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
