The lichens and mosses help to form soil by secreating acids on the rocks they cling to, also when lichens die they create soil so that one day the soil can support grasses that can support brushes and shrubs which can support, red alders then doug firs then cedars and hemloch
Pioneer organisms are the first organisms to colonize a barren environment in primary succession. They play a crucial role in breaking down rock and soil, helping to create the conditions necessary for other plant and animal species to establish and thrive. Their presence helps to kickstart the process of ecosystem development in these harsh environments.
Primary succession is important because it is the process by which new ecosystems develop on bare rock or soil where no life previously existed. This helps to create diverse habitats for various plant and animal species to thrive. Primary succession also plays a critical role in soil formation and nutrient cycling, contributing to overall ecosystem health and resilience.
Pioneer species play a crucial role in primary succession by being the first plants or organisms to colonize barren or newly formed habitats. They are typically hardy and can tolerate harsh environmental conditions, helping to break down rocks and build up soil through processes like organic matter accumulation and root growth. This sets the stage for more complex plant and animal communities to establish in the ecosystem over time.
Nitrogen cycling is more important during primary succession. This is because nitrogen availability often limits plant growth in early successional stages, and nitrogen-fixing bacteria play a key role in making nitrogen available for plant uptake. Carbon cycling becomes more important as vegetation establishes and organic matter accumulates.
Soil is not strictly necessary for secondary succession, but it plays a crucial role in facilitating the process. Secondary succession occurs in areas where a disturbance has removed existing vegetation but left the soil intact, such as after a forest fire or agricultural abandonment. The presence of soil provides nutrients and a seed bank, allowing for quicker regrowth of plants compared to primary succession, which starts on bare rock or completely barren surfaces. Therefore, while soil enhances and accelerates secondary succession, it is not an absolute requirement.

Both primary and secondary succession begin with pioneer species that are able to colonize and establish in harsh environments with little to no soil. These pioneer species play a crucial role in breaking down rock or creating soil, which paves the way for other plant species to gradually establish and diversify the ecosystem.
I'm not doing your homework for you.

Lichen is a composite organism consisting of a symbiotic relationship between fungi and algae or cyanobacteria. As such, they do not fit neatly into traditional trophic levels, as they are not strictly consumers, producers, or decomposers. Instead, they play a unique role as primary producers in ecosystems by converting sunlight and nutrients into energy through photosynthesis.
they play the part of making sure the primary consumers don't over populate.
A lichen is a hybrid of a fungus and an algae. In the arctic the lichen must be exceptionally sturdy. The algae providing the food through photosynthesis and the fungus extracts available water to forma symbiotic relationship.
some are mushrooms, bacteria, or even some wild fungi
The primary food source for a predator is other animals. Predators play a crucial role in the ecosystem by controlling the population of prey species, which helps maintain a balance in the ecosystem.
