Answer:
lichens
mycorrhiza
Explanation:
Lichens are formed by two types of organisms- an alga and fungus. The mycelium of the fungus forms athin mat which offers anchorage and protection to some microscopic algae. The alga provides the fungus with sugars which it produces through photosynthesis.
Mycorrhiza is a type of symbiotic relationship between a saprophytic fungus and vascular plants such as coniferous trees. The fungus develops in the soil near the base of the tree. Some of the hyphae penetrate into the outer layers into the soil from which it obtains mineral ions. It also decomposes proteins to their amino acids. The fungus shares these nutrients with its tree host.
