Detailed explanation-1: -In lichens, the interaction between algae and fungi is a symbiotic relationship. Algae feed fungi that lack chlorophyll pigments. Fungi, on the other hand, help algae by providing protection and aiding in water absorption.

Detailed explanation-2: -Lichens are commonly recognized as a symbiotic association of a fungus and a chlorophyll containing partner, either green algae or cyanobacteria, or both. The fungus provides a suitable habitat for the partner, which provides photosynthetically fixed carbon as energy source for the system.

Detailed explanation-3: -The lichen symbiosis is thought to be a mutualism, as both the fungi and the photosynthetic partners, called as photobionts, benefit.

Detailed explanation-4: -Two common mutualistic relationships involving fungi are mycorrhiza (fungi and plant roots) and lichen (fungi and either cyanobacteria or green algae).

Detailed explanation-5: -Lichen is a symbiotic association between algae and fungi. The chlorophyll containing algae prepare and provide food to the fungi. In return, the fungi provide shelter, water and minerals to algae.
