What stage of primary succession do lichen grow on exposed rock?

Lichen are one of the first organisms to colonize exposed rock in the early stages of primary succession. They can break down the rock and contribute organic material to the soil, helping create conditions for other plants to establish and grow.


What will happen if a rock is eroded in a place where there is no soil?

You know how the soil grows plants like in the rock but if there is no soil then the plant won't grow in the rock.


What happens when a rock is exposed to a chemical?

Rock exposed to very high temperature and pressure will soften or melt.


What are the pioneer organisms on a bare rock?

Pioneer organisms on a bare rock are typically lichens, mosses, and algae. These organisms can survive in harsh conditions and help break down the rock surface, creating soil for other plants to grow. Over time, these pioneer species can pave the way for more complex vegetation to establish itself on the rock.


What component of the soil will exposed rock eventually weather to form?

Exposed rock will weather to form minerals in the soil through a process called physical and chemical weathering. This process breaks down the rock into smaller particles that mix with organic matter to become part of the soil's mineral content.


Why is succession is slower on sand or bare rock than previously vegetated soil exposed by fire?

Succession is slower on sand or bare rock than on previously vegetated soil exposed by fire. This is because the fire burned everything but the nutrients are still there.


Are common organisms that grow on rock and cause weathering?

Lichens are common organisms that grow on rock and contribute to weathering through their physical and chemical actions. Lichens produce acids that can break down rock material, facilitating the process of weathering over time. Their presence can help break down rocks into smaller particles, contributing to soil formation.


Do all plants have to grow in soil?

No some grow in the ocean i think seaweed grow in holes of the rock


Bedrock?

Is a solid layer of rock lying beneath Earth's soil layer. Bedrock: Is the source of rock and mineral fragments that make up soil. Is not weathered if it is not exposed to wind and water. 


What is the mixture of mineral and rock particles remains of organism water and air?

The mixture you are describing sounds like soil, which consists of mineral and rock particles, organic matter from decaying organisms, water, and air. Soil is vital for supporting plant growth and providing nutrients for ecosystems.


Describe how soil organisms affect soil?

it makes it easier or more difficult for plants to grow by affecting the availability of things they need.


What is the name of disturbance that removes most of the organisms and damages the soil?

The term for the disturbance that removes most organisms and damages the soil is "clear-cutting" in the context of forests. This practice involves the removal of all trees in a specific area, leaving the soil exposed and vulnerable to erosion.
