Doversity In Living Organism Flashcards
…………is the raw material for adaptation in species
Genetic biodiversity
…………variety of living organism present in a particular region or earth
Biodiversity
………is a way to measure diversity that is important to human health and hazards
Chemical biodiversity
Wht ecosystem in north America went into extinction
Prairie ecosystem
Science Hv names for what amount of eukaryotic species
1.5 million out of 8.7 million
Wht is endemic
When a species can only be found in one location
Biodiveristy increases as latitude……
Decreases
Biodiversity increases closer to the
Equator
Biodiveristy is the greatest in the
Tropics
Number of endemic species is greatest in
Tropic
………is the study if distribution of species both in the past and present
Biogeography
Types of biogeoegraphy
Ecological
Historical
Conservational
Types of biodiversity
Genetic and conservation biodiversity
Ecological
Species biodiversity
………is important to the survival and welfare of human population
Biogeography
………is the father of taxonomy
Carolus Linnaeus in 1958
Certain features or properties used for the classification of living organi
Charcteristics
Systems of classification are
Artificial…base on observable characteristics
Natural….base on similarity
Phylogenetic…….base on evolutionary and genetic relationship
Different classification system
Two kingdom classification
Five kingdom classification
…….is a group of organism that can reproduce among themselves
Species
Hierarchical naming of humans
Kingdom.....Animalia Phylum.....Chordata Class..........mammalian Order.........primate Family........Hominidae Genus.........homo Species........sapiens
Major characteristics for classifying organism
Type of cellular organization(whether prokaryotic or eukaryotic)
Body structure of cells(unicellular or multicellular)
Mode of obtaining food(autotrophs or heterotroph)
……..given by car Linnaeus is use for naming different animals
Binomial nomenclature
………brings abt biodiverification of living organism
Evolution
Charles darwin first describe the idea of evolution in his book…….. And on the yr……..
Origin of species
1839
Older simple organisms are called
Primitive or lower organism
Younger complex organisms are called……..
Advanced and higher organism
