The slow metabolism and excretion of DDT lead to severe ecological consequences, including population declines in affected carnivores, as trace amounts in primary producers like plankton become exponentially concentrated as they ascend the food chain.

Whereas some protist species are essential components of the food chain and generators of biomass, others function in the decomposition of organic materials. Still other protists are dangerous human pathogens or causative agents of devastating plant diseases.

In about 30 percent of cases, however, the trypanosome causes further damage, especially to the heart and digestive system tissues in the chronic phase of infection, leading to malnutrition and heart failure due to abnormal heart rhythms.
