What is a mutualistic relationship?
When both organisms benefit from the relationship.

Earthquakes, volcanic eruptions, and tsunamis can destroy habitats and kill individuals regardless of how many are present. (True or false)

How does evolution occur?
Evolution has been identified by Charles Darwin as the process of NATURAL SELECTION.
Evolution favours a desired trait (giraffe's long neck), these traits are more likely to survive, therefore these animals are more likely to produce offspring with the same characteristic.
