  1. KEY CONCEPTProkaryotes perform important functions for organisms and ecosystems.

  2. Power Notes Describe two ways bacteria provide nutrients to humans. Which two gasses do bacteria help recycle in the ecosystem? -Make Vitamins -Break down food -Food Production (i.e. yogurt and pickles) Define bioremediation Give an example of bioremediation and describe how it works.

  3. Prokaryotes provide nutrients to humans and other animals. • Prokaryotes live in digestive systems of animals. • make vitamins • break down food

  4. yogurt, cheese • Bacteria help ferment many foods. • pickles, sauerkraut • soy sauce, vinegar

  5. Power Notes Describe two ways bacteria provide nutrients to humans. Which compounds do bacteria help recycle in the ecosystem? -Make Vitamins -Break down food -Food Production (i.e. yogurt and pickles) -Oxygen -Nitrogen -Carbon -Sulfur Define bioremediation Give an example of bioremediation and describe how it works.

  6. Prokaryotes play important roles in ecosystems. • Prokaryotes have many functions in ecosystems. • photosynthesize • recycle carbon, nitrogen,hydrogen, sulfur • fix nitrogen

  7. Power Notes Describe two ways bacteria provide nutrients to humans. Which two gasses do bacteria help recycle in the ecosystem? -Make Vitamins -Break down food -Food Production (i.e. yogurt and pickles) -Oxygen -Nitrogen -Carbon -Sulfur Define bioremediation Give an example of bioremediation and describe how it works. Process that uses microbes and other living things to break down pollutants Bacteria can digest oil from an oil spill and break it down into harmless chemicals.

  8. Gulf oil spill
