How do protists affect human life?
Some severe diseases of humans are caused by protists, primarily blood parasites. Malaria, trypanosomiasis (e.g., African sleeping sickness), leishmaniasis, toxoplasmosis, and amoebic dysentery are debilitating or fatal afflictions.
How do protists benefit the environment?
Saprobic protists have the essential function of returning inorganic nutrients to the soil and water. This process allows for new plant growth, which in turn generates sustenance for other organisms along the food chain.
How are protists helpful and harmful?
The kingdom Protista is a diverse group of organisms. Some protists are harmful, but many more are beneficial. These organisms form the foundation for food chains, produce the oxygen we breathe, and play an important role in nutrient recycling. Many protists are economically useful as well.
What protists are beneficial?
Brown and Red Algae Phaeophyta, or brown algae, are also beneficial types of protist. These include algae such as kelp. These algae are food sources for fish as well as humans. They have large amounts of iodine, which is a necessary nutrient for life.
How do protists infect humans?
The parasites enter the body through food or water that has been contaminated by feces of infected people or animals. The protozoa attach to the lining of the host's small intestine, where they prevent the host from fully absorbing nutrients. They may also cause diarrhea, abdominal pain, and fever.
What are the roles of protists?

What is the evolutionary importance of protists?
What is the evolutionary importance of protists? Scientific evidence points to that eukaryotic organelles as mitochondria and chloroplasts originated as prokaryotes that first lived within larger prokaryotic cells. Therefore, the protists evolved from the prokaryotic cells.
