The sources of pathogens can be abiotic; soil water, animals or other humans 28 of 31 Host An organisms that serves as nutrient source for a parasite 29 of 31 Parasite An organisms that lives in/off an other organisms without providing any benefit to the host 30 of 31 Vector An organisms that transmits a parasite via feeding off another organism 31 of 31
