What are the three levels of biodiversity -CORRECT ANSWER 1) species diversity
2) genetic diversity
3) ecosystem diversity
Genes -CORRECT ANSWER Units of inherited information that determine specific
characteristics or functions
Biodiversity -CORRECT ANSWER The variety of life in the world
Genetic diversity -CORRECT ANSWER The sum of all the different forms of genes
present in a particular species. It also helps the survival of species
Species -CORRECT ANSWER A population whose members can breed freely in nature
and produce fertile offspring
Why do farmers grow a single type of corn? -CORRECT ANSWER It allows farmers to
use the same equipment, fertilizers and techniques on their land
Monocultures -CORRECT ANSWER Genetically uniform farms, that usually have little
or no biodiversity
Species diversity -CORRECT ANSWER The variety of species and relative abundance
of the species in a given area. This allows ecosystems to survive environmental
changes such as droughts, plagues or disease outbreaks
Ecosystem diversity -CORRECT ANSWER The diverse range of habitats, the various
organisms that live in the habitats and the relationships that connect them
What kind of organisms or processes does biodiversity help maintain? -CORRECT
ANSWER 1) ecosystem cycle carbon, nitrogen and oxygen
2) micro-organisms make nutrients available and break down toxic substances in water
and soil
3) insects, bats, and other animals pollinate flowering plants and crops
,4) ecosystems clean air, purify water, control erosion,more vent floods and modify
climate
Keystone species -CORRECT ANSWER Species that have a disproportionately large
effect on the ecosystem in which they live, such as a honeybee
What is malaria -CORRECT ANSWER A deadly disease that is spread through
mosquitoes infecting people. It is called by a microscopic parasite called plasmodium,
that transmits this disease through it's bite
Why use scientific naming for animals? -CORRECT ANSWER To reduce confusion
among different languages around the world, and to have a universal scientific name to
each known species
Dichotomous key -CORRECT ANSWER A tool used by scientists and non-scientists to
identify organisms with which they are unfamiliar
What does the work "dichotomous" mean in Greek? -CORRECT ANSWER "To cut in
two"
What does a dichotomous key posses -CORRECT ANSWER It possesses a series of
questions about an organism, and each question asks users to choose between two
possible characteristics that the organism may have
Taxonomy -CORRECT ANSWER The science of naming, identifying, and classifying
species
Binomial nomenclature -CORRECT ANSWER A system for naming specific species,
which became the most used classification system in biology, invented in 1750 by the
Swedish botanist Carolus Linnaeus
What are the two main parts of the binomial nomenclature -CORRECT ANSWER 1) a
two-part Latin name
2) a hierarchy or ordering of the species into broader and broader groups
Binomial -CORRECT ANSWER The two-part Latin name that is part of the binomial
nomenclature
Genus -CORRECT ANSWER The first part of the specie's name, to which the species
belongs
What are the 8 groups of the binomial nomenclature -CORRECT ANSWER 1) domain
2) kingdom
3) phylum
4) class
5) Order
, 6) family
7) genus
8) species
Biodiversity -CORRECT ANSWER The variety of life in the world or a particular habitat
or ecosystem
Ecosystem -CORRECT ANSWER a specie's environment
Taxonomy -CORRECT ANSWER Science of naming, identifying and classifying
species
Protist -CORRECT ANSWER Eukaryotic organisms that do not fit into the animal, plant
or fungi kingdoms
Cilia -CORRECT ANSWER Short, hair-like structures protruding from a cell that move
fluid and particles over the cell's surface; sometimes used for movement and food
gathering
Flagella -CORRECT ANSWER Long, whip-like structures that some cells use for
movement
Pseudopodia -CORRECT ANSWER Cellular extensions of streaming cytoplasm that
enable a cell to move in the direction of that extensions
Mycorrhizae -CORRECT ANSWER Fungus that forms a mutualistic association with
roots of a plant
Phylogenetic tree -CORRECT ANSWER A branching diagram that represents the
evolutionary relationships among species or groups
Clade -CORRECT ANSWER An evolutionary branch on a phylogentic tree
Phylogeny -CORRECT ANSWER The evolutionary development and history of a
species or group of organisms
Morphology -CORRECT ANSWER Study of form and structure of organisms
Habitat loss -CORRECT ANSWER The greatest threat to biodiversity, where animals
loos their homes
Fragmentation -CORRECT ANSWER splitting a habitat into fragments, which may
prevent species from using resources in all parts of the habitat
Deforestration -CORRECT ANSWER Clear-cutting trees
