What are fossils?
Fossils are the imprints of parts of organisms that have become preserved in rocks after death.

What is cassifying?
Classifying living organisms is called taxonomy. It puts organisms into groups or "taxa".
3 of 15
What is an outlier?
An outlier is a data point which is separate from the rest of the data. It can be used to identify a problem with the theory being applied to interpret the data. Statistical tests can be carried out to see whether outliers are significantly different

What is biodiversity?
Biodiversity is biological diversity. It is the variety of life on earth.

What is a habitat?
A habitat is a physical environment where a living organism lives. Many species may have to share a habitat.
6 of 15
What is an ecosystem?
An ecosystem is made up of the variety of organisms interacting with eachother and the environment in which they live. An ecosystem may encompass many habiats.

What is a niche?
A niche is used to describe an organism's position and needs within an ecosystem. The environmental space is defined by habitats climate, competitors, position in the food chain, space, shelter etc.

What is species diversity?
Species diversity refers to the number and distribution of differnt species in an area.
9 of 15
What is genetic diversity?
Genetic diversity of a population includes that diversity of allels and the number of organiams that have a combination of two different allels. It is a result of the recombination of alleles during sexual reproduction, mutations and natural selction

What does ex-situ mean?
Ex-situ means off site. Ex-situ conservation is where animals are taken from thier natural habitat and put in a \zoo or wildlife enclosure.

What does in-situ mean?
In-situ mans on site. In-situ conservation is where an endangered plant or animal species is protected in its natural habitat.

What is sustainable development?
sustainable development is meeting the needs of the present generation without compromising the ability of fuure generations to meet thier needs.

What are logarithms?
logarithms are used to handle values which range over several orders of magnitude. for example log 1000= 3, log 2= 2, log 10= 1. this shows a logarithmic scale. A change of one unit corresponds to a x10 change in the value of the data.

What is a biodiversity hotspot?
A biodiversity hotspot is an area identified as containing at least 1500 species of higher plants which are endemic to that area. The ecosystem must have lost at least 70% of its original habitat.
