How many types of ecological succession are there?

• 3

• 2

• 4

• 1

What are the two types of ecological succession?

• Primary and Secondary

• Environmental and Natural

• Habitat and Community

• Population and Community

What do we call a species that colonizes an area first?

• Primary species

• Starter species

• Beginning species

• Pioneer species

Which of these organisms may grow in the beginning of primary succession?

• shrubs and trees

• grass and shrubs

• lichen and moss

• grass and weeds

How is primary succession different from secondary succession?

• Primary succession is faster and has pioneer species.

• Primary succession takes longer and starts in a new area without soil.

• Secondary succession has soil and starts with trees

• Secondary succession occurs after a disturbance and is slower that primary succession.

What type of succession would occur after a forest fire?

• Beginning succession

• Primary succession

• Secondary succession

• Biological succession

What type of succession would occur after a volcanic lava flow in an area?

• Primary Succession

• Secondary succession

• Biological succession

• Volcanic succession

Which group of organisms shows the proper order of appearance for primary succession?

• trees, lichen/mosses, grasses/weeds, bushes/shrubs

• bushes/shrubs, grasses/weeds, lichen/mosses, trees

• lichen/mosses, bushes/shrubs, grasses/weeds, trees

• lichen/mosses, grasses/weeds, bushes/shrubs, trees

Why can secondary succession start with organisms like grasses and weeds?

• because seeds were blown in by the wind.

• because there is already a layer of soil.

• because it is faster.

• because the ground is softer.

What continues to increase over time during ecological succession?

• biodiversity

• the area

• pioneer species

• the soil
