Answer

  1. Lichens.

Explanation:

Lichens are symbiotic association between fungus (mycobiont) and alga (phycobiont). The mycobiont is usually an ascomycete and phycobiont is mostly blue green alga or green alga. Lichens can grow in extremely inhospitable conditions. In many ecosystems they are the pioneer species. The role of mycobiont is to provide body structure, anchorage to plant and absorption of minerals and water. Phycobiont provides food to fungus through photosynthesis.
