Ecological Succession Review with a Holiday Twist!

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a climax community.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment, initiating the process of ecological succession.

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

How does species diversity change during succession?

Back

As ecological succession progresses, the number of species typically increases, leading to greater biodiversity.

Front

What role do lichens play in primary succession?

Back

Lichens are often the first organisms to colonize bare rock, helping to break it down and contribute to soil formation.

Front

What is the significance of soil in ecological succession?

Back

Soil provides essential nutrients and a habitat for plants and animals, allowing for the establishment of more complex communities.

Front

How can fire be beneficial to ecosystems?

Back

Fire can clear out dead vegetation, promote new growth, and help certain species to germinate, thus playing a crucial role in maintaining ecosystem health.

Front

What is a disturbance in an ecosystem?

Back

A disturbance is an event that disrupts the structure or function of an ecosystem, such as fire, flooding, or human activities.
