Biological Communities Jimmie Whitney Lucy Flower Vocational High School 18907 Jonathan Lane 3545 West Fulton Blvd Homewood, Illinois 60430 Chicago, Illinois 60624 (708) 957-4019 (312) 534-6767 Objectives: 1. List familiar organisms found in several different communities. 2. Distinguish between producer and consumer organisms in your list. 3. Examine and identify as many organisms as possible from a soil community. Materials Needed: l. soil sample 2. newspaper 3. vials 4. hand lens 5. four small jars (baby food) with cover 6. isopropyl alcohol or methyl alcohol Procedure: You are probably used to thinking of your city, town or neighborhood as a community. But did you know that all animals and plants live in communities too? Part A. Based on your knowledge and previous observations, list in table form, at least four organisms found in these communities: Home, Farm, Forest, Ocean and Pond. Identify the organisms as producers or consumers. Circle the organisms that you consider to be consumers. Producers are usually green in color and are capable of producing their own food. Consumers are usually brown or other color and cannot manufacture their own food. They obtain food by eating or consuming. Part B. Soil Community Collect a variety of soil samples. Place each sample in a plastic bag to prevent drying and then label the bag. Vegetation found on the soil must be included with the sample. Divide students into four groups. Give each group a sample of soil and a sheet of newspaper. Empty the bag of soil on the sheet of newspaper. Probe through the soil and look for hidden organisms. Record in table form the common names of all observed consumer and producer organisms. Record the approximate numbers of each type of organism that is listed. Place small consumer organisms into containers (jars) of isopropyl alcohol for future microscopic study.Return to Biology Index
