Ecological Succession: Nature's Great Grit

The video uses The Lion King to introduce ecological succession, explaining primary and secondary succession. Primary succession occurs in new areas without soil, starting with pioneer species like lichen. Secondary succession happens in areas with existing soil after disturbances. The video highlights the importance of biodiversity and encourages curiosity.

What is the main theme of the introduction in relation to The Lion King?

• The depiction of animal behavior

• The role of music in storytelling

• The concept of ecological succession

• The importance of family

In ecological terms, what is a community?

• A single organism

• A group of the same species

• Multiple populations living together

• An ecosystem

What characterizes primary succession?

• It involves pioneer species in a new area without soil

• It is faster than secondary succession

• It is caused by human activities

• It occurs in areas with existing soil

Which of the following is a pioneer species in primary succession?

• Grass

• Rabbits

• Lichen

• Oak trees

How does secondary succession differ from primary succession?

• It occurs in areas where soil is already present

• It requires pioneer species to create soil

• It starts in a new area without soil

• It takes longer to reach a climax community

What is a key factor that makes secondary succession faster than primary succession?

• Human intervention

• Lack of biodiversity

• Absence of competition

• Presence of existing soil

Why is biodiversity important in ecological succession?

• It prevents natural disasters

• It reduces competition

• It speeds up the succession process

• It supports a stable ecological community
