CLASSIFICATION Flashcards
Biodiversity
the variety of all life forms. Different plants, animals, fungi and microorganisms, the genes they contain, the ecosystems they’re part of Biodiversity is the amount of variation within a group: can be broken up into three groups
Ecosystem biodiversity
The variety of ecosystems on earth (marine, terrestrial)
Species diversity
the variety of species in the area (fauna, plants)
Genetic biodiversity
the range of different genes in the group and the size of the gene pool
Biodiversity hotspots
these are biologically diverse and ecologically distinct regions under threat
Endemic
native or restricted to a particular area
Species
A member of a group of similar organisms that are capable of interbreeding to produce fertile offspring
Adaption
the process whereby traits that are beneficial in terms of survival and reproduction become more common
Ecosystem
is a biological community of plants, animals and other organism living in an area which provides what they need in order to survive: DETERMINED BY SPECIES, SPECIES INTERACTIONS AND ABIOTIC FACTORS
Biodiversity distribution
the degree of variation- biodiversity is not evenly distributed, it relies on abiotic factors. Biodiversity reflects how well an ecosystem functions. The higher the species diversity, the more stable the ecosystem.
Abiotic factors
non-living factors contributing to the distribution of species including; sunlight, oxygen concentration, climate, rainfall ph levels, carbon dioxide levels, soil type
Biome
A broad regional type of ecosystem, characterised by distinctive climate and soil conditions and a distinctive kind of biological community (tundra or arid)
Gene
a segment of DNA or RNA that carries genetic codes for the manufacture of proteins essential for growth and development of each living organism
Community
the plants, animals and micro-organisms which live together in a particular place at a particular time
Habitat
the place in an environment where a particular plant or animal lives
