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

Open Ended

Which type of ecological succession is occurs faster? Primary or Secondary Succession? Explain.

Multiple Choice

A series of progressive changes in the composition of an ecological community over time

• Climax Community

• Primary Succession

• Ecological Succession

• Species Richness

Multiple Choice

A measure of both species richness and relative number of species.

• Species diversity

• Species richness

• Biodiversity

• Keystone species

Multiple Choice

a change or disturbance of the environment most often caused by human influences and natural ecological processes.

• Environmental Change

• Evidence Of Evolution

• Trophic Level

• Natural Selection

Multiple Choice

an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

• Pioneer species

• Ecological succession

• Climax community

• Secondary succession

Multiple Choice

newly exposed or newly formed rock is colonized by living things for the first time. Certain hardy plants and lichens with few soil requirements, called pioneer species, colonize the area first.

• Climax community

• Primary succession

• Ecological succession

• Secondary succession

Multiple Choice

A species that has a disproportionately large effect on community structure relative to their abundance.

• Pioneer Species

• Invasive Species

• Keystone Species

• Foundation Species

Multiple Choice

usually modify the environment so that it can support the other organisms that form the community.

• Pioneer Species

• Foundation Species

• Invasive Species

• Keystone Species

Multiple Choice

any change in the environment, that can modify the composition, structure, or function of an ecological community

• Ecosystem

• Secondary Succession

• Disturbance
