The activity of an Enzyme is affected by its environmental
conditions. Changing these alter the rate of reaction caused
by the enzyme. In nature organisms adjust the conditions of their
enzymes to produce an Optimum rate of reaction where necessary
or they may have enzymes which are adapted to function well in
extreme conditions where they live.
They could discover which organisms are closely related to the mammoth, and which one is the most closely related.
An example of decomposers in the desert could be worms, beetles, or bacteria. Decomposers can't always stay alive because of the drought. Good luck!!
