Ecological succession

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, initiating the ecological succession process.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of species replacements.

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, characterized by a diverse array of species.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

Front

What role do lichens play in primary succession?

Back

Lichens are often the first organisms to colonize bare rock in primary succession, helping to break down the rock and create soil.

Front

What is the order of species appearance in primary succession?

Back

The order typically starts with pioneer species like lichens, followed by mosses, then grasses, and eventually shrubs and trees.

Front

What are biotic factors in an ecosystem?

Back

Biotic factors are the living components of an ecosystem, including plants, animals, fungi, and microorganisms.

Front

What are abiotic factors in an ecosystem?

Back

Abiotic factors are the non-living physical and chemical components of an ecosystem, such as sunlight, temperature, water, and soil.

Front

How does a disturbance affect an ecosystem?

Back

Disturbances can reset ecological succession, leading to secondary succession if soil remains, or primary succession if the area is barren.
