Explain why genetic diversity is important to the survival of a species (3 marks) 28. A pitcher plant (Sarracenia purpurea) is an Ontario bog plant with leaves that hold water in which various organisms live. Is a pitcher plant a species or an ecosystem? Explain (3 marks) 29. There has been a recent increase in the number of parents who are choosing not to vaccinate their children.
