Succession & Biodiversity

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What role do lichens play in primary succession?

Back

Lichens help to break down rock and contribute to soil formation, making them crucial pioneer species in primary succession.

Front

Define pioneer species.

Back

Pioneer species are the first organisms to colonize previously uninhabited land, initiating the process of ecological succession.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil and some organisms still exist, such as after a forest fire.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession.

Front

Give an example of a pioneer species in primary succession.

Back

Mosses and lichens are common examples of pioneer species that help establish soil.

Front

What is an invasive species?

Back

An invasive species is a non-native species that is introduced to an area and can disrupt local ecosystems.

Front

How do shrubs contribute to succession?

Back

Shrubs can provide habitat and food for various animals, and they help improve soil quality, facilitating further succession.

Front

What is the order of plant growth after a volcanic eruption?

Back

The order is Lichens → Grasses → Shrubs → Trees.

Front

What is the significance of soil in primary succession?

Back

Soil is essential for supporting plant life, and its formation is a key milestone in primary succession.
