Lichens are the first organisms to appear in primary succession because they are able to colonize bare rock surfaces and begin breaking it down into soil through their ability to produce acids that break down minerals. Lichens are also able to survive in harsh environmental conditions, making them well-suited to establish themselves as pioneer species in the initial stages of primary succession.
they are the last organisms to appear.
The first organisms to appear in an ecological community are typically pioneer species, which are often hardy plants or microorganisms that can thrive in harsh conditions. These organisms, such as lichens and mosses, help to stabilize the environment and improve soil quality, paving the way for more complex communities to develop. They initiate the process of ecological succession, ultimately leading to a more diverse and stable ecosystem.
Pioneer species. These organisms are typically the first to establish themselves in a previously uninhabited or disturbed habitat, paving the way for other species to colonize the area. Pioneer species are often well-adapted to harsh conditions and play a crucial role in ecological succession.
Lichens are often the first organisms to colonize areas after a volcanic eruption because they are highly resilient and can thrive in harsh environments with minimal nutrients. They are symbiotic associations between fungi and algae or cyanobacteria, allowing them to photosynthesize and obtain moisture from the air. Their ability to tolerate extreme conditions helps them break down the bare substrate, paving the way for other plants and organisms to establish themselves over time.
The first organism to grow on a new volcanic island is typically pioneer species such as lichens, mosses, or algae. These organisms are able to establish themselves in harsh environments and begin the process of soil formation, which prepares the area for more complex plant species to grow.

lichens are called pioneer organisms because they are the first type of organisms that started to live in a certain forest or such. For example, If a volcanic island were to appear in the middle of the ocean. It is devoid of life at first. Certain organisms will land on the island either by washing up on the volcanic ash or land on it after being carried by the wind currents. One of these organisms would be a lichen. Lichens are considered pioneer because they will begin to destroy the rock and ash producing soil. They can survive because a lichen is a mutualistic relationship between a fungus and an algae. Once these lichens have done their work other organisms will appear, bacteria, algae, various grasses, etc. This is called ecological succession.

Lichens are the first to appear.
As far as I know, there are no fungi capable of making their own food. All fungi are heterotrophs. Lichens appear to be an exception, but lichens are a composite of two organisms. The fungus in a lichen is still considered a heterotroph as it relies on it's photosynthetic partner for food.

They are the first organisms to appear on the bare rocks in an area after a volcanic eruption, fire, or rock slide has occurred.
