Biodiversity (Ocr A Level Biology) Study Guide Questions And Correct Answers

What Is Done by Zoos to Help Maintain Genetic Diversity? {Ans: Breeding programs have logbooks with details of each animal in the program. It is then decided which animals should be paired for breeding. This reduces inbreeding}What Is Ex-situ Conservation? {Ans: Conservation off site involves protecting species by relocating part of the population from a threatened habitat to a new location.}Advantages of Ex-situ Conservation {Ans: - It can be used to protect individual animals in a controlled environment. - Variables such as hunting, competition for food/space, etc., can be more easily controlled and managed. - It is possible to check on individuals' health. - Breeding can be manipulated.}What does a value close to 0 mean {Ans: -the habitat has a low biodiversity -the habitat is dominated by one or a few species -the habitat is unstable and may be severely damaged by disruption -habitat may be man made}What Is In-situ Conservation? {Ans: Conservation on site involves protecting species in their natural habitats.}What Is a Habitat? {Ans: The area inhabited by an organism/species. It includes the physical factors (e.g., soil, temperature range) and the living factors (e.g., food availability, presence of predators).}
