Succession Notes New ones

Multiple Choice

Why is the process of succession important for ecosystems?

• It helps maintain biodiversity and ecosystem stability.

• It decreases the amount of biomass over time.

• It prevents any changes in the ecosystem.

• It leads to extinction of all species.

Multiple Choice

What is an example of primary succession?

• A beach

• A forest fire

• A pond

• A grassland

Multiple Choice

What is an example of secondary succession?

• A forest fire

• A new island forming

• A glacier retreating

• A desert forming

Multiple Choice

Which stage in ecological succession is characterized by the presence of lichens and mosses on bare rock?

• Pioneer stage

• Intermediate stage

• Climax community

• Secondary succession

Multiple Select

Which of the following are characteristics of secondary succession?

• Occurs on bare rock

• Begins after a disturbance

• Soil is already present

• Involves pioneer species

Multiple Choice

How does succession affect the biomass of an ecosystem over time?

• Biomass decreases

• Biomass remains constant

• Biomass increases

• Biomass fluctuates randomly

Hotspot

Select what kind of succession the following example represents:

A volcano erupts in the middle of the ocean. As the lava flows into the ocean, new rock is formed.

Match

Match the following

• An ecosystem must start over from scratch. The soil is completely destroyed, and it takes longer for the ecosystem to rebuild.

• An ecosystem experiences a pause in growth due to a catastrophic event, the ecosystem takes awhile to rebuild.

• For example: a volcanic eruption

• For example: a wild fire.
