Measuring Biodiversity

Species Evenness is a measurement of:

• the number of different species in a community

• Having even numbers each species is in a community or ecosystem.

• how spread out the species are in a community

• How rare the species are in a community

Species Richness is a measurement of:

• the number of different species in a community

• how close in numbers each species is in a community or ecosystem

• how spread out the species are in a community

• How rare the species are in a community

Which community has higher Species Evenness?

• Sample 1

• Sample 2

• They are both equal

• I can't tell

''Variety of species or richness in the number of species in an ecosystem throughout the entire biosphere.''

This statement refers to which type of diversity?

• Genetic diversity

• Ecosystem diversity

Why are ecosystems with high biodiversity considered healthier?

• Healthy ecosystems have more insects that feed everything else

• Healthy ecosystems tend to make bigger animals

• High biodiversity allows ecosystems to be more resilient to changes

• High biodiversity means the area is looked after people
