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.

Scientists attempted to determine the evolutionary relationships between three different finch species, A, B, and C. In order to do this, they examined the physical characteristics and DNA of these species. DNA was extracted from all three species and analyzed using gel electrophoresis. The results are shown in the diagram. Which statement best describes the method used above to determine the evolutionary relationships between three species of finches?

• Examine the structure of the beaks and compare them.

• Observe behavioral and physical characteristics of all the finches and group them by similarities.

• Obtain molecular evidence from all three species and identify similarities.

• Compare common ancestors of all three of the species to see if they are the same.

Species richness refers to (a)   in an ecosystem.

• The number of different ecosystems

• The number of individuals within an ecosystem

• number of different species in an ecosystem

• The number of dominant species in an ecosystem

Match the following terms with the correct definition -

• A species of animal or plant that is seriously at risk of extinction.

• Endangered Species

• The cumulative changes in a population or species over time.

• Invasive species

• The number of different species present in an ecosystem.

• Genetic diversity

• An organism that is not native to the area in which it is introduced and has no natural predators.

• Evolution

• The total number of genetic characteristics in the genetic makeup of a species.

• Species diversity

Match the following terms with their definition.

• the most abundant species

• Species Dominance

• the relative abundance of species

• Species Richness

• the total # of different species

• Species Evenness

Why is it important to preserve Botana curus? (Choose all that apply)

• We could lose the source of the genetic material if it becomes extinct

• The extinction of this species could lead to the extinction of another species

• It could be used for other medicinal properties

• The local people will have no plants to eat

• It will make the environment look like a desert
