Biodiversity can relate to a range of habitats, from a small local habitat to the Earth
Biodiversity means the variety of living organisms in an area. Scientists measure it at any scale — from a single pond to the whole planet.
Real World
The Amazon rainforest holds roughly 10% of all species on Earth, while a single garden pond in England may contain over 100 invertebrate species — both are valid scales for measuring biodiversity.
Exam Focus
When a question specifies a habitat scale, match your answer to that scale — do not generalise to global biodiversity.
