WebEvery organism in an ecosystem relies on other species for survival: 2.)Reduced options for mates can lead to inbreeding: 3.) Decreased diversity can lead to increased susceptibility to disease: 4.) The loss of a producer could result in the loss of consumers: 5.) When a population becomes small, diversity is lost: Many of the environmental events that contribute to an extinction vortex do so through reduction in population size. These events can include rapid loss of population size due to disease, natural disasters, and climate change. Habitat loss and/or habitat degradation can also kick start an extinction vortex. Other factors include events that occur more gradually, such over-harvesting (hunting, fishing, etc.), or excessive predation. rawlings catching equipment
