AQA A LEVEL BIOLOGY - BIODIVERSITY Questions With
Accurate Answers
What is a community? - Accurate answers All the organisms of different species living in a habitat
What is a habitat? - Accurate answers Place where an organism lives
What is biodiversity? - Accurate answers the variety of life in the world or in a particular habitat or
ecosystem.
What increases biodiversity? - Accurate answers diverse physical habitats, moderate disturbances,
variations in temperature and precipitation and many trophic interactions
and higher variety of foods
What 2 things are needed to calculate biodiversity? - Accurate answers The number of different
species
The number of individuals of each species
Why is there a higher biodiversity in natural ecosystems compared to artificial ones? - Accurate
answers In artificial ecosystems pesticides, herbicides and fertilisers are used
How does woodland clearance reduce biodiversity? - Accurate answers It is done to increase
farmland area, reducing the number of trees and tree species. It also destroys habitats and so reduces
the variety of habitats and food source sources and this causes animals to migrate and die
How does hedgerow removal reduce biodiversity? - Accurate answers It is done to turn lots of
small fields into bigger fields. It reduces number of small trees and plants so reduces the variety of
habitats and food source sources and this causes animals to migrate and die
How does use of herbicides reduce biodiversity? - Accurate answers It reduces number of small
trees and plants so reduces the variety of habitats and food source sources and this causes animals to
migrate and die
