21.                        Below is a diagram of a pond showing the three layers of microbes. Place these bacteria and algae in the correct level, and after their names tell how they produce food.

****Anoxygenic Photosynthetic Bacteria, photosynthetic bacteria, methanogens, Cyanobacteria, sulfate reducers, heterotrophs, algae****

Top layer

Second layer

Third layer

Fourth layer

22.                      Name two microscopic animals that live in the pond.______________________________

27. Where do Mycorrhizal fungi live?______________________ What is their job?_____________________________

28. Thinking question. Farmers often plant corn on land that land that has been planted in soybeans or alfalfa for the previous 2 or 3 years. They save money on fertilizer by doing this.
