Biodiversity is a key concept in ecology and has importance on both local and global scales. Biodiversity is the degree of variation of life, or put more simply, the number of different individuals and lifeforms in an area. Scientists usually measure biodiversity on either the genetic, species, or ecosystem levels. For example, if you wanted to measure the biodiversity of beetles on a global scale, you would find that there are over 350,000 known species of beetles on the planet. However, if you wanted to measure the biodiversity of beetles locally, you might only find 10 or 20 species. The reason for this difference is that biodiversity varies greatly with the location, habitat, and species being surveyed. In general terms, biodiversity tends to be highest at the equator, and decrease at higher latitudes - i.e as you get further away from the equator. Knowing this information, where would you expect to find the habitats with the lowest biodiversity?

Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In this video we look at how to simplify algebraic fractions, and how to add and subtract them. VISIT us at www.fuseschool.org, wh
CREDITS Animation & Design: Peter van de Heuvel Narration: Lucy Billings Script: Lucy Billings The word polygon comes from Greek. Poly means “many” and Gon means “angles”. Polygon = many angles. Polygons are 2-dimensional shapes, that are made of straight lines, with all the sides joined up. VISIT
In algebra we have lots of different names for different things: expressions, equations, formulae and identities are all slightly different versions of similar things. Then within these, we have variables, constants, coefficients and exponents to describe the different parts. We also need to know wh
