Ecological Succession

What is a community in ecology?

• A living organism

• A group of the same species in a given area

• A group of different species in a given area

• A group of plants in a given area

What is primary succession?

• The growth of plants and animals after a disturbance

• The process of organisms in an ecological community over time

• The colonization of a new area without any soil

• The increase in biodiversity in an ecological community

What are pioneer species in primary succession?

• Large trees

• Animals that move into a new area

• Small plants that colonize first

• Organisms that break down rock into soil

What comes after pioneer species in primary succession?

• Grasses and weeds

• Shrubs

• Trees

• Animals

Why does primary succession take a long time?

• Because it involves a disturbance like a forest fire

• Because it requires the growth of pioneer species

• Because it involves the colonization of a new area without soil

• Because it takes hundreds of years for a climax community to form

What is secondary succession?

• The colonization of a new area without any soil

• The process of organisms in an ecological community over time

• The growth of plants and animals after a disturbance

• The increase in biodiversity in an ecological community

What is the key difference between primary and secondary succession?

• The presence of soil

• The types of pioneer species

• The speed of the process

• The types of disturbances

What is more likely to be a faster process, primary or secondary succession?

• Primary succession

• Secondary succession

• Both take the same amount of time

• It depends on the type of disturbance

Organize these options into the right categories: Sort the environments into the categories that they would be a part of.
