Ecological niche, biodiversity, and extreme/unstable environments

Organisms with a specialised ecological niche (e.g. coral-eating butterfly fish)...

• have a narrow range of food requirements
• live in a specific habitat

Organisms with a general ecological niche (e.g. tuna)...

• have a wide range of food sources
• live in a wide range of habitats

High biodiversity → species tend to occupy narrow ecological niches

• High biodiversity means many different species living in one…
