What type of succession are pioneer organisms involved?
they are the last organisms to appear.
The first organisms to live in a new habitat are called?
The first organisms to appear in an area undergoing succession are known as the pioneer species. These organisms lead to a more biodiverse steady-state ecosystem.

Why is a lichen most likely to be a pioneer species?
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.

What are all of the types of fungi that makes its own food?
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.

abandoned fields or forest clearings
