What Is Biodiversity? | Ecology & Environment | Biology | FuseSchool
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?

In this video you'll learn the basics about Ionic Bonds.
The Fuse School is currently running the Chemistry Journey project - a Chemistry Education project by The Fuse School sponsored by Fuse. These videos can be used in a flipped class
In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value.

Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case.
There are different types of tropisms: Positive tropisms are when growth is towards the stimulus - so the plant growing towards the light to maximise the stimul
