Multiple Choice

Why do algae blooms happen?

Biodiversity

Howard 2022

Students will be able to tell what the difference is between areas of high genetic diversity and areas of low genetic diversity when disruptions occur in ecosystems

• High biodiversity - Many plants and animals in an area.

• Low biodiversity - Low amount of plants and animals in an area​

​

​Some text here about the topic of discussion.

Biodiversity

​High - Many variations in DNA between members of the same species

Low - Few variations in DNA between members of the same species​

Genetic Diversity

​High - Many type of different species in the same area

Low - Few types of different species in the same area ​

Species Diversity

High - Many types of habitats for organisms to live

Low - Few types of habitats for organisms to live​

Ecosystem Diversity

​

Multiple Choice

Which of the following best describes the relationship between biodiversity

and stability of ecosystem?
