Which two characteristics show variation as a result of inherited factors only?
blood group
pierced ears
number of freckles
natural eye colour
height
Define ecosystem diversity
variety of environments and their organisms in a given area
variation of genes within a species or population in a given area
variety of life in Earth's land, freshwater, and marine ecosystems
changes to an ecosystem that affect how the parts of it interact
Which statement best describes an example of low species diversity?
A population of frogs has a wide variety of skin colors
A marsh ecosystem is covered by a single species of cattail bulrushes
A state park includes multiple forest, wetland, and freshwater ecosystems
A group of organisms that are similar enough to be in the same category that can reproduce together to pass on their genes.
Organism
Species
Breed
These moths are all the same species. The differences between their wings is an example of ________________
diversity within species
diversity between species
Which habitat has the highest species richness?
A
B
C
More information is needed
As you increase the latitude (get closer to the poles), what happens to the biodiversity?
increases
decreases
does not change
Levels get increasingly specific from?
kingdom to species
phylum to genus
mammalia to family
order to family
Which species tend to go extinct more frequently?
narrow niche creatures
broad niche creatures
the differentiation of niches that enables similar species to coexist in a community
character displacement
climax community
resource partitioning
pioneer species
The ecological niches of three bird species are shown in the diagram. What is the advantage of each bird species having a different niche?
As more birds feed higher in the tree, available energy increases.
More abiotic resources are available for each bird.
Predators are less likely to feed on birds in a variety of locations.
There is less competition for food.
Ostriches and gazelles feed next to each other and watch for predators, alerting each other to danger. Since the visual abilities of the two species are different, they each can identify threats the other animal would not as readily see. This is an example of -
Mutualism
Commensalism
Parasitism
Predation
What is the primary focus of biological diversity?
Variety of life forms in different ecosystems
Chemical composition of organisms
Physical structure of organisms
Genetic makeup of a single organism
Which of the following is an example of genetic diversity?
Different species of birds in a forest
Variety of genes within a population of wolves
Multiple ecosystems in a national park
A single species of fish in a lake
How does habitat destruction affect biodiversity?
Increases genetic variation
Decreases species diversity
Has no effect on ecosystems
Promotes new species formation
