Ecology Succession

The building up of an ecosystem after lava or glaciers have left nothing but rock.

• Secondary Succession

• Primary Succession 

• Natural Selection

• Adaptation

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Which of the following best describes the climax community in ecological succession?

• A community that is constantly changing and evolving.

• A stable and mature community with little change in species composition.

• A community dominated by pioneer species.

• A community that has just begun the process of succession.

What is the difference between primary and secondary succession?

• Primary succession already has soil.

• Primary has soil and secondary does not

• soil is present in both

• primary has no soil and secondary has soil

Why does primary succession take longer to reach climax community?

• Because trees do not perform photosyntheses.

• Because climax community is in a forrest.

• Because primary succession already has soil

• Because primary succession does not have soil

Which of the following is an example of a pioneer species in primary succession?

• Oak tree

• Lichen

• Pine tree

• Grass

What is the primary difference between primary and secondary succession?

• Primary succession occurs on bare rock surfaces, while secondary succession occurs in areas where soil is already present.

• Primary succession is faster than secondary succession.

• Secondary succession occurs on bare rock surfaces, while primary succession occurs in areas where soil is already present.

• There is no difference between primary and secondary succession.

What is the most important function of pioneer species?

• To create rocks

• To create soil and add nutrients to the environment 

• To look nice

• Food for animals
