Lichens Contribute to Soil Formation. Lichens thrive in undisturbed sites where nothing else will grow. They grow on rocks, barren soil and the bark of dead or live trees. Lichens are not parasitic when they grow on trees, they just use the tree bark as a home. They enrich the soil by trapping water, dust and silt. When lichens die they contribute organic matter to the soil, improving the soil so that other plants can grow there. Lichens Fix Nitrogen
Bacteria are an important part of the soil. They are able to capture some nu-. trients that plants cannot. When living things die, bacteria play a very important role as. decomposers, bacteria and fungi feeding on and breaking down plant and animal matter.ara-Protozoans are microscopic organisms that usually live in water. They move through the water with tiny hair-like arms called cillia. The cillia are located all around the sack-like body of the protozoa and wave back and forth to move the protozoa through the water. Some protists are producers like plants.
