the variability within species, between species, and between ecosystems

22. Why Is Biodiversity Important?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play
Important for all species' survival
We need a variety of habitats for all the different species because each species is adapted to a certain set of environmental conditions.

23. Why Is Biodiversity Important?
All species depend on each other to survive
so if one becomes extinct another species that relies on it could go extinct as well
Individual traits can allow some species to adapt to environmental changes,
but many species cannot adapt if their habitat and food chains are greatly altered
