CIE A2 Biology Ch 18 - Biodiversity,
Classification & Conservation Terms Exams
species - Correct Answers ✅a group of organisms with similar
morphology and physiology, which can breed together to produce
fertile offspring and are reproductively isolated from other species
ecosystem - Correct Answers ✅all the living organisms of all species
(the biotic component) and all the non-living organisms (the abiotic
component) that are found together in a defined area and that interact
with one another
niche - Correct Answers ✅the role of an organism in an ecosystem
habitat - Correct Answers ✅the place where an organism, a
population or a community lives
biodiversity - Correct Answers ✅the variety of ecosystems and
species in an area and the genetic diversity within species
endemic species - Correct Answers ✅a species only found in a
particular area and nowhere else
species richness - Correct Answers ✅the number of species in a
community

species diversity - Correct Answers ✅all the species in an ecosystem
genetic diversity - Correct Answers ✅all the alleles of all the genes in
the genome of a species
distribution - Correct Answers ✅how different species are spread
throughout an area
abundance - Correct Answers ✅the number of individuals of a
species in an area
species frequency - Correct Answers ✅measure of the chance of
finding a particular species in a given area
species density - Correct Answers ✅Measure of how many
individuals there are per unit area
classification - Correct Answers ✅the arrangement of animals and
plants in taxonomic groups according to their observed similarities
taxonomy - Correct Answers ✅the study and practice of
classification, which involves placing organisms in a series of taxonomic
units (taxa) to form a hierarchy
