Primary and Secondary
The normal GRADUAL
(takes a long time)
changes that occur in the types of species that live in an area.
The rocks need to break down to make the soil before new species will grow
These are the FIRST species to grow
They can be different depending upon the area. Example: is it a forest, a pond, a wetlands….?
AND- is it primary or secondary succession?
The key is whether there is soil already present or does the soil need to be made from broken down rock
Lichens-do not need soil to survive
They can survive drought, extreme heat and cold, and other harsh conditions and start the soil building process.
Algae- many types
Second plants to become established after the disturbance (taller grasses, small shrubs).
