It’s like you living in Chocolate cake!
AP Biology Fungal Diversity Chytridiomycota Zygomycota Basidiomycota Ascomycota Fungi
AP Biology Ecological Roles Decomposers recycle nutrients Symbiotic Relationships lichen fungi + algae cyanobacteria or green algae pioneer species in ecosystems makes soil from bare rock mycorrhizae fungi + plants enables plants to absorb more water Lichens are fungi that have discovered agriculture!
AP Biology Mycorrhizae Critical role in plant growth extends water absorption of roots without mycorrhizae with mycorrhizae EctomycorrhizaEndomycorrhiza
