Ecological Succession

Starts with BARE ROCK followed by lichen:

• Primary succession

• Secondary succession

• Both primary and secondary succession

• Neither primary nor secondary succession

What type of ecological succession is shown in this picture?

• Primary

• Secondary

• Tertiary

• Quaternary

The final stable community of plants and animals is called a(n) --

• pioneer community.

• farmland.

• climax community.

• old field.

How do lichens contribute to primary succession?

• Lichens decompose organic matter from animals and plants.

• Lichens begin to break down rock to form soil.

• Lichens are nitrogen fixing bacteria.

• Lichens convert carbohydrates into fossil fuels.

Which type of ecological succession will typically reach a climax community faster because soil is already present?

• Primary succession

• Secondary succession

• Both types of succession

• Neither type of succession

• Mosses and lichens

• Grasses

• Small plants
