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.
I don't think so because in my science text book it states that mosses and lichens are the first organisms to start growing in an environment again and pioneer species have to be the first species to arrive. After the mosses grow then die decaying matter builds up on them and other plants can grow. Hope this helped :)
When the pioneer species die, their remains are used as an anchor area and a nutrient source for the next species to populate the area.
Pioneer species
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

Organisms in a species have characteristics that differ from those of other organisms in their genus.

If we look back at the basics, all that it takes for succesion to occur is a pioneer species. In the tundra, the most common pioneer species is arguably mosses and lichens. Other plants will grow off of the pioneer species.
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.
Perennial grasses do not really inhibit the growth of pioneer species. If the grass, or any other species are well watered, treated with vitamins and see plenty of sun, they will do well.
species is the group of organisms
On the Antarctic continent, there are no organisms or species that compliment each other.
