Succession Interactive Flashcard

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 are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

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 ecosystem but left the soil intact, such as after a forest fire.

Front

What is a pioneer species?

Back

A pioneer species is the first species to colonize a barren environment during the initial stages of ecological succession.

Front

Give an example of a pioneer species.

Back

Lichens and mosses are common examples of pioneer species.

Front

What role do producers play in ecological succession?

Back

Producers, such as plants, are essential in ecological succession as they create energy through photosynthesis and provide food for other organisms.

Front

Why are lichens important in primary succession?

Back

Lichens help to break down rock and create soil, making it possible for other plants to grow.

Front

What happens to pioneer species as succession progresses?

Back

As succession progresses, pioneer species are often replaced by larger, more competitive plant species.

Front

What factors contribute to the replacement of pioneer species?

Back

Larger plants compete for resources like space, sunlight, and soil nutrients, which allows them to outcompete pioneer species.
