Biodiversity

Variation in same species (e.g. skin colour, height)

The range of inherited characteristics within a group (e.g. snakes skin)

If none of the individuals had the traits to survive this change they will die However if there is variation, some individuals may have suitable traits that allow them to survive

Variation of different species, and number of individuals within a species (e.g. 10 species, 500 individual) For a healthy ecosystem, different species can allow for more interactions and less disruption when a species is lost

Mosquitoes consuming blood

Low fish using toxic anemone to hide

Bird eating scraps in the teeth of a crocodile

Certain animals have a extra stomach for eating grass

Barnacles on a whale

Plants need organisms to spread their pollen

Variety of ecosystems and range of shapes/sizes in a habitat Diversity ensure that a wide variety of species can survive on earth, the interaction helps maintain a healthy planet
