What is the typical order of growth on a newly formed volcanic island?

The typical order of growth is: Lichen, Grass, Shrub, Tree.

Front

How does the time required for primary succession compare to secondary succession?

Back

Primary succession takes more time than secondary succession.

Front

What is secondary succession?

Back

Secondary succession is a pattern of change that occurs after an existing ecosystem is disturbed or destroyed, such as through clearing for farming.

Front

When do oak trees typically grow in the succession process?

Back

Oak trees are typically one of the last species to grow in the succession process.

Front

What role do lichens play in ecological succession?

Back

Lichens are often the first organisms to colonize bare rock, helping to break it down and create soil for other plants.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil remains.

Front

What factors can influence the rate of ecological succession?

Back

Factors include the type of disturbance, climate, soil quality, and the availability of species to colonize the area.

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

How do disturbances affect ecological succession?

Back

Disturbances can reset the succession process, leading to secondary succession and altering the composition of the ecosystem.
