Measuring Biodiversity

Measuring Biodiversity

By: Teacher Thess

Biodiversity

It is refers to the number and variety of species that live in an ecosystem.

It measure of the health of an ecosystem.

Multiple Choice

Image "B" shows more biodiversity than image "A". Why?

• Because "B" shows more different species than image "A"

• Because image "B" has less different species than "A"

• "A" has a greater number of same species plants so this statement is wrong.

• Both images show the same biodiversity

Multiple Choice

What does biodiversity mean?

• Only one species in an area.
• The different amount of species in an area
• All abiotic life
• Nitrogen fixation

Components of biodiversity

• Species diversity

• ecosystem diversity

• Genetic diversity

• Functional diversity

Species diversity

It is related to the number of the different species and the number of individuals of each species with any community,

Ecosystem diversity

Genetic diversity

Functional diversity

Functional diversity is a component of biodiversity that generally concerns the range of things that organisms do in communities and ecosystems.

Multiple Choice

It is the number of different species that are represented in a given community

• species diversity

• functional diversity

• genetic diversity

• ecosystem biodiversity

Multiple Choice

It is a component of biodiversity that generally covers the range of functional traits of microorganisms prevailing in an ecosystem.

• species diversity

• functional diversity

• genetic diversity

• ecosystem biodiversity

Multiple Choice

It is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species.

• species diversity

• functional diversity

• genetic diversity

• ecosystem biodiversity

Multiple Choice

It deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment.

• species diversity

• functional diversity

• genetic diversity

• ecosystem biodiversity

Multiple Choice

An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans.

• True

• False

Biodiversity can be measured in two ways:

• Species richness

• Simpson's diversity index

Species richness

It refers to the number of species living in an ecosystem.

It takes account of the number of individuals f each species present.

It is only concern with th population.

Which community is more diverse?

Simpsons diversity index

• It is the measure of biodiversity, which covers not only the species richness but also even distribution of different types of species in the ecosystem

How do you determine the number of species in a certain area?

Do you need to count it all?
