What is ecological succession?

• A species that is first to establish itself in an area.

• a series of predictable changes that occur in a community over time.

• A stable, mature community.

• A process which involves living organisms breaking down bare rock.

What is the function of a pioneer species?

• To prepare the forest for a natural disturbance.

• To scout out an area and see if it is suitable for growth.

• The break down exposed rock and other nutrients into soil.

• To establish a relationship between two ecosystems.

What is a difference between primary and secondary succession?

• Primary succession results in a climax community, whereas secondary succession results in a destroyed community.

• Primary succession starts with bare rock, whereas secondary succession starts with an already established community of plants.

• . Primary succession takes a shorter amount of time because it begins with already established soil, whereas secondary succession takes a longer period of time because it begins with bare rock.

• Primary succession takes a longer period of time because it begins with bare rock, whereas secondary succession takes a shorter amount of time because it begins with already established soil.

Which of the following is an example of a long-term environmental change?

• A hurricane

• The clearing of an extreme amount of trees - deforestation

• A factory polluting a nearby lake

• A flood

What is true about long-term environmental changes?

• Many long-term environmental changes are due to predictable weather patterns and happen quickly.

• Long-term environmental changes never cause lasting effects in an area.

• Many long-term environmental changes affect organisms over many generations.

• Long-term environmental changes are usually predictable and easy to avoid.
