KEY CONCEPTProkaryotes perform important functions for organisms and ecosystems.
Prokaryotes provide nutrients to humans and other animals. • Prokaryotes live in digestive systems of animals. • make vitamins • break down food • fill niches
yogurt, cheese • Bacteria help ferment many foods. • pickles, sauerkraut • soy sauce, vinegar
Prokaryotes have many functions in ecosystems: • They photosynthesize • They recycle carbon, • They recycle nitrogen, hydrogen and sulfur, • They “fix” nitrogen
Bioremediation uses prokaryotes to break down pollutants. • oil spills • Bacteria are responsible for breaking down biodegradable materials.
