A group of individual organisms very similar in apperance, anatomy, physiology, biochemistry and genetics, whose members are able to interbreed freely to produce fertile offspring.
1 of 28
Habitiat
The place where an organism lives.
2 of 28
Biodiversity
The variety of life - the range of living organisms o be found.
3 of 28
Random sampling
Studying a small part of the habitat and assuming it contains a representative set of species that can be applied to the whole habitat. The sample site must be chosen t ransom.
4 of 28
Species richness
The number of species present in a habitat.
5 of 28
Simpson's diversity index
A formula used to measure the diversity or a habitat.
6 of 28
Biological classfication
The process or sorting living things into groups. Natural classification does this byb grouping things according to how closely realted they are. Natural classification refkects evoluionary relationshps.
7 of 28
Taxonomy
The study of the principles of classifiaction.
8 of 28
Phylogeny
The study of the evolutionary relationship between organsims.
9 of 28
Prokaryotes
Have no nucleus.
10 of 28
Protocists
Include all the organisms that don't fit into the oher four kingdoms. Many are single-celled, but some are multicellular.
11 of 28
Fungi
Organisms that are mostley saprophytic. They consist of a mycelium with walls made of chitin.
12 of 28
Plants
Multicellular organism that gain their nutrition from photosynthesis.
13 of 28
Animals
Heterotrophic multicellular eukaryotes.
14 of 28
Binomial system
Use two names to identify each species: the genus name and the species name.
15 of 28
Dichotomous key
Uses a series of questions with two alternative answers to hel you identify a specimen.
16 of 28
Variation
The presence of variety - of differences between indiiduals.
17 of 28
Genetic Variation
Caused by differences between he genes and the combinations of genes or alleles.
18 of 28
Continuous variation
Varation in which there is a full range of intermediate phenotypes between two extreames.
19 of 28
Discontinuous variation
Variation in which therer are discrete groups of phenotypes whith no or very few individuals in between.
20 of 28
Adaptation
A feature that enhances survival and long-term reproductive success.
21 of 28
Xerophytic
Plants are adapted to living in very dry conditions.
22 of 28
Natural selection
The 'selection' by the environment of particular individuals that show certain variations. These individuals will survive to reproduce and pass on their variations to the next generation.
23 of 28
Speciation
The formation of a new speceis.
24 of 28
Extinction
When a species ceases to exist.
25 of 28
Conservation in situ
Means conserving a species in its noramsl environment.
26 of 28
Conservation ex situ
Means conserving an endangered species by activities that take place outised its normal environment.
27 of 28
Environmental impact assessment (EIA)
A procedure to assess the likely significant effect that a proposed development may have on the environment.
