What are the charateristics of ecological succession?
The basic thing to know, is the primary succcesion occurs w/o any dirt presnt. The pioneer species, lichens and mossess, break down any rocks present to create soil. Secondary succesion occurs when there is already soil present, but the land has been cleared, like after a fire.
Lichens and mosses erode rocks by producing?
Lichens and mosses erode rocks by producing acids. These acids lead to the deterioration of rocks, such as limestone and marble.
What kinds of plants grow on rocks?
Lichens...Ivy.
How do mosses and lichens help to from soil?
Lichens and mosses help to form soil by breaking down the rocks that they are attached to.
What role does lichen play in primary succession?
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
Primary succession?
Plnats grow on rocks like lichens and mosses.
At what stage of primary succession do lichens start to grow on exposed rocks?
pioneer plant stage
Which parts of the ecosystem had to be establishes before the primary succession could occur?
The parts of the ecosystem that had to be established before the primary succession shown in the transparency could occur is the lichens, rocks and soil...also that the mosses, ferns, shrubs, and grasses are parts of the primary succession.

How do lichens contribute to soil formation?
Lichens work by picking up nutrients to help them produce and also pick up water to help the grow and live longer.
Lichens and mosses erode rocks by producing?
Lichens and mosses erode rocks by producing acids. These acids lead to the deterioration of rocks, such as limestone and marble.
What organisms grow on the sides of trees and on rocks and logs?
Organisms that grow on the sides of trees, rocks, and logs are often various types of lichens and mosses. Lichens are a symbiotic association between fungi and algae or cyanobacteria. They can be found on a variety of surfaces, including tree bark, rocks, and soil. Mosses are small, non-vascular plants that thrive in moist environments, and they are commonly found on the sides of trees, rocks, and logs. Both lichens and mosses play important roles in ecological processes and contribute to the biodiversity of their habitats.
Are lichens growing on rocks competition?
no
How can lichens cause chemical weathering?
Nanovolumes of acids released from lichens react with rocks and minerals.
How do lichens affect the environment?
lichens affect the enviroment by breaking down rocks in primary succsesion
What was the first plant to grow on the world?
no definitive evidence exists to demonstrate a "first" plant, and as such it is impossible to answer this question.
What type of succession takes place after lava from a volcanic eruption covers an area?
the lava and ash deposited during a volcanic eruption breaks down to provide valuable nutrients for the soil
