IV. Fungal Partnerships Two symbiotic relationships with fungi are critical to ecosystems: Label the amoeba diagram. (pg. 550) 1. Mycorrhiza: mutualistic relationship between plants and fungi. Fungi transfers minerals from the soil to plants, and plants supply carbs to the fungus. Organize facts about amoebas in the chart below: (pg. 543, 550) Phylum Excretion method Habitats Feeding method 2. Lichen: a symbiosis between a fungus and a photosynthetic partner like green algae or cyanobacteria. Lichen inhabit extreme environments, like rocks, bare soil, and tree trunks, which makes them critical for primary succession. Lichens are also used to monitor air quality.
