Answer: A
Notes:
Explanation:
Statement 1 is correct: Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The outer skin and internal structure of a lichen is made of strands of fungal hyphae. Interspersed among the strands inside the lichen are individual cells of algae.
Statement 2 is incorrect: Lichens do not have roots or structures like other plants, they depend on the atmosphere for air and water. So, the quality of ambience reflects in the diversity of lichens.
