If pepsin and trypsin had to function together, which ph would produce the highest activity? how is this answer found?

The proper environments for Pepsin are acidic, particularly those with a pH of 1.5 to 2. Optimal operating pH for Trypsins is of about 8. It seems that the highest level of activity for the two if they were in the same environment would have to be midway between their optimum range - about pH 5.

There are three energy level in the energy pyramid. The producers have the 100% energy and the primary consumers feed on the producers and obtain 10% energy the producers have and secondary consumers feed on the primary consumers.

The energy left at this level is 10% of the energy that primary consumers have.

Hence, Producers will have 475,650 kilocalories

Primary consumers will have 475,65 kilocalories

Secondary consumers will have 4756.5 kilocalories
