18.5 Beneficial Roles of Prokaryotes
KEY CONCEPTProkaryotes perform important functions for organisms and ecosystems.
18.5 Beneficial Roles of Prokaryotes
Define bioremediation Give an example of bioremediation and describe how it works.
Which two gasses do bacteria help recycle in the ecosystem?
Describe two ways bacteria provide nutrients to humans.
Power Notes
-Make Vitamins-Break down food-Food Production (i.e. yogurt and pickles)
18.5 Beneficial Roles of Prokaryotes
Prokaryotes provide nutrients to humans and other animals. • Prokaryotes live in digestive systems of animals.
– make vitamins– break down food
18.5 Beneficial Roles of Prokaryotes
• Bacteria help ferment many foods.– yogurt, cheese– pickles, sauerkraut – soy sauce, vinegar

Define bioremediation Give an example of bioremediation and describe how it works.
Which compounds do bacteria help recycle in the ecosystem?
Describe two ways bacteria provide nutrients to humans.
Power Notes
-Make Vitamins-Break down food-Food Production (i.e. yogurt and pickles)
-Oxygen-Nitrogen-Carbon-Sulfur
18.5 Beneficial Roles of Prokaryotes
Prokaryotes play important roles in ecosystems.
• Prokaryotes have many functions in ecosystems. – photosynthesize – recycle carbon, nitrogen,
hydrogen, sulfur – fix nitrogen
