question 1 - 15
lichens are an important pioneer species. what would a lichen contribute as a pioneer species? (sc.912.l 17.4)
absorption of water for use by consumers
decomposition of rock to create soil
production of food for producers.
reabsorption of oxygen for consumers.

Explanation:

Pioneer species are the first species to colonize barren environments. Lichens are composite organisms consisting of a fungus and an alga or cyanobacterium in a symbiotic relationship. They can secrete acids that break down rock, a process called chemical weathering. Over time, this breakdown of rock contributes to the formation of soil. Consumers (like animals) do not use lichens for water absorption in the context of pioneer species' role. Producers (like plants) do not get food from lichens in this regard. And lichens do not reabsorb oxygen for consumers as their main pioneer - species function.

Answer:

Decomposition of rock to create soil.
