A physical factor that influences an ecosystem is called an "abiotic factor."

The last step in the blood clotting is the formation of a fibrin clot.
Thrombin is the serine protease (protein) enzyme which activates fibrin.
It converts the soluble fibrinogen into the insoluble fibrin which then results in the blood coagulation.
