What are the three levels of biodiversity - (ANSWER)1) species diversity
2) genetic diversity
3) ecosystem diversity
Genes - (ANSWER)Units of inherited information that determine specific
characteristics or functions
Biodiversity - (ANSWER)The variety of life in the world
Genetic diversity - (ANSWER)The sum of all the different forms of genes present
in a particular species. It also helps the survival of species
Species - (ANSWER)A population whose members can breed freely in nature and
produce fertile offspring
Why do farmers grow a single type of corn? - (ANSWER)It allows farmers to use
the same equipment, fertilizers and techniques on their land
Monocultures - (ANSWER)Genetically uniform farms, that usually have little or no
biodiversity
,Species diversity - (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 - (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? -
(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 - (ANSWER)Species that have a disproportionately large effect
on the ecosystem in which they live, such as a honeybee
What is malaria - (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? - (ANSWER)To reduce confusion among
different languages around the world, and to have a universal scientific name to
each known species
,Dichotomous key - (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? - (ANSWER)"To cut in two"
What does a dichotomous key posses - (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 - (ANSWER)The science of naming, identifying, and classifying species
Binomial nomenclature - (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 - (ANSWER)1) a two-
part Latin name
2) a hierarchy or ordering of the species into broader and broader groups
Binomial - (ANSWER)The two-part Latin name that is part of the binomial
nomenclature
, Genus - (ANSWER)The first part of the specie's name, to which the species
belongs
What are the 8 groups of the binomial nomenclature - (ANSWER)1) domain
2) kingdom
3) phylum
4) class
5) Order
6) family
7) genus
8) species
Biodiversity - (ANSWER)The variety of life in the world or a particular habitat or
ecosystem
Ecosystem - (ANSWER)a specie's environment
Taxonomy - (ANSWER)Science of naming, identifying and classifying species
Protist - (ANSWER)Eukaryotic organisms that do not fit into the animal, plant or
fungi kingdoms
