Biodiversity and Evolution

Biodiversity - Range of species in a given area (or number)

Describe the biodiversity of the planet Earth .

The bioversity is high in the equator and is low in the poles.

Explain the pattern.

• Colder at the poles.
• Hotter at the equator.
• Enzyme have highest rate of reaction at around 37 oC      ( Optimum level ).
• A range of species can survive.

Evolution - The development of one species to another over a very long period of time.

Natural Selection - The selective pressure selects for the weakest member of species." Survival Of The Fittest ".

Adaptation - When a species characteristics are suited to its enviroment e.g. Colour of an organism allows them to camoflauge.
