Ecological Succession

Ecological Succession

We will observe, record, and describe the role of ecological succession such as in a microhabitat of a garden with weeds by viewing the PowerPoint Presentation.

I will observe, record, and describe the role of ecological succession such as in a microhabitat of a garden with weeds by answering questions with 100% accuracy.

Multiple Select

Choose which of the following answers describe primary succession (may be more than one answer)

• starts with no soil

• starts with soil

• takes centuries to occur

• takes decades to occur

Pioneer Species

Pioneer (first ones there) Species are plant organisms that can grow on rock.

Lichen and Mosses are the pioneer species of primary succession.

Lichen and Mosses

Lichen and mosses produce acids that break down rock into its component minerals.

The Lichen and mosses then use these minerals to grow.

The rock minerals mixed with the organic debris of the lichens and mosses start the formation of soil.

Multiple Choice

The growth of which of the following usually occurs first in primary succession on a bare rock?

• grasses

• trees

• lichens

• shrubs

Multiple Choice

What is the role of the pioneer species in primary formation.

• to provide oxygen for the environment

• to provide a habitat for insects

• to break down rock and start the formation of soil

• to provide color for the environment

Multiple Select

Choose which of the following answers describe secondary succession (may be more than one answer)

• starts with no soil

• starts with soil

• takes centuries to occur

• takes decades to occur
