Succession Review

Which type of succession is a process that brings life into a previously uninhabited area?

• cyclic succession

• seasonal succession

• secondary succession

• primary succession

What type of succession is likely to occur immediately following a tsunami that caused significant soil erosion?

• secondary succession because all the soil was lost in the tsunami

• secondary succession because some soil will still be left behind after the tsunami

• primary succession because the tsunami killed so many organisms in this ecosystem

• primary succession because there were still some organisms that survived to recover the ecosystem

How do mosses and lichens most contribute to succession?

• They are producers in the food chain.

• They break down rock into soil.

• They increase the amount of oxygen in the surrounding air.

• They become plants.

A final, stable community in equilibrium with the environment is a

• pioneer species

• secondary succession

• urban village

• climax community

A species that colonizes an uninhabited area and that starts an ecological cycle in which many other species become established is a

• extinct species

• succession species

• pioneer species

• new species

What type of vegetation below would appear first in a secondary succession event?

• trees

• grasses

• saplings

• shrubs

The main difference between the start of primary succession and secondary succession is

• Primary succession has soil at the beginning and secondary succession does not

• Primary succession begins quickly and secondary succession begins slowly

• Secondary succession only has two stages and primary succession has six stages

• Secondary succession has soil at the beginning and primary succession does not

Which of the following are most likely to be the pioneer organisms on an area of bare rock?

• trees

• shrubs

• lichens

• perennial grasses

What is ecological succession?

• gradual change in living communities that follows a disturbance

• rapid change in a nonliving community

• a change that occurs in a community overnight

• how an ecosystem is changed into livable land for humans

Primary Succession starts with

• a barren area, no soil

• land that was previously inhabited

• already has soil

• a clear cut piece of land
