Ecology 2.1: Biodiversity

What is Biodiversity?

• The study of life

• A living organism

• The variety of life on Earth

• A non living organism

What are the three features biodiversity is built on?

• Genetic, community, habitat

• Genetic, ecosystem, species

• Genetic, population, species

• Genetic, ecosystem, population

How do biodiversity and stability work together?

• The lower the biodiversity the greater the stability of an ecosystem.

• The higher the biodiversity, the less stable the ecosystem

• The higher the biodiversity, the greater the stability of the ecosystem.

• Biodiversity has nothing to do with ecosystem stability.

High biodiversity is 

• having a lot of the same organism.
• having a few of the same organism.
• having a lot of variety of different organisms.
• only having one of each organism. 

Which ecosystem is more likely to survive a change in the environment?

• One with High biodiversity

• One with Low biodiversity

The level of biodiversity that involves a variety of habitats is _____ diversity.

• ecosystem

Greater ____________________ means there are more habitats to support different types of organisms.
