Question 1

Three levels of biodiversity:

Answer 1

■ 1) Genetic diversity
■ 2) Species diversity
■ 3) Ecosystem diversity

Question 2

Genetic Diversity

Answer 2

the sum of all the different forms (i.e. alleles) of genes present in a particular species

Question 3

Species Diversity

Answer 3

the variety and relative abundance of species in a given area (i.e. an ecosystem)

Question 4

Ecosystem Diversity

Definition: a diverse range of habitats, the organisms that live in those habitats, and the relationships that connect them
