module17REVIEW

In this module, we learned that species differ in their tolerance to abiotic conditions and that the range of abiotic and biotic conditions that allow survival, growth, and reproduction all help to determine where a species can live. Past changes in environmental conditions have altered species distributions and caused extinctions. Future environmental changes are expected to have similar effects.
