Classification 1
The system of grouping organisms and ecosystems to show biological relationships.
What is classification?
The groups in order from largest to smallest.
What are kingdom, phylum, class, order, family, genus, species.
A group of organisms related to each other including the ancestor and offspring.
What is a clade?
A type of sampling that breaks a community down into similar groups.
What is stratified sampling?
A tool to identify organisms using pairs of characteristics.
What is a dichotomous key?
The naming and classification of organisms into groups and taxa.
What is taxonomy?
The 5 kingdoms.
What are protista, plantae, fungi, animalia and monera?
This is used to determine the relatedness based on differences in proteins structure between species.
What is mutation rate?
Carefully chosen strata results in less error, lower variation and lower standard error.
What are advantages of stratified sampling?
This encompasses all of the species present on earth.
What is biodiversity?
Linnaeus developed this system which gives every organism a unique Genus species name based on physical characteristics.
What is binomial naming?
The three domains.
What are Bacteria, Archaea and Eukarya?
Over time DNA changes due to mutation and can be compared to determine relatedness.
What is DNA hybridisation?
A line or belt through a study area.
What is a transect?
This biome has nutrient poor soil, high rainfall, dense vegetation and high biodiversity.
What is a rainforest?
Individuals that are different because they can't breed to produce viable offspring.
What is a biological species?
Organisms that are short lived, reproduce quickly and don't care for their offspring.
Who are r-strategists?
A process that compares genomes between species to determine relatedness.
What is DNA sequencing?
A square or rectangular area where vegetation is sampled.
What is a quadrat?
This biome has less than 500mm of rain annually, sparse vegetation and low biodiversity.
What is a desert?
Groups within a species that are physically unique and spread along a large geographical range.
What is a subspecies?
Organisms that are long lived, produce fewer offspring and look after their young.
Who are K-strategists?
Branching diagrams that show evolutionary relationships.
What are phylogenetic trees?
Large numbers of samples, randomly selected, with calibrated equipment.
How to minimise bias?
A fish that eats a prawn which eats an algae.
What is a second order consumer?
