Ecological niche, biodiversity, and extreme/unstable environments

HideShow resource information

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…
