- Environments with low frequency and intensity of disturbance tend to have ________ species diversity because ______. Group of answer choices A) low; the best competitors exclude any other species B) high; disturbances kill off a large number of individuals C) low; there are fewer late-successional species than early-successional species D) high; more species can colonize over a longer period of time Question: Answer choice selection is either: Burkina Faso or Italy for all three answer choicesarrow_forwardDetermine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardchoose the correct alternative on the biotic potential influences:a) the average number of offspring producedb) the size of the individualsc) mortalityd) migration ratearrow_forward
