Which of the following serve as means for ex-situ conservation of rare and endemic plant and animal species respectively?

Botanical garden and zoological parks serve as means for ex-situ conservation of rare and endemic plant and animal species. Botanical gardens are specialised gardens that have collections of living plants for reference. Plant species in these gardens are grown for identification purposes and each plant is labelled indicating its botanical/scientific name and its family.Zoological parks are the places where wild animals are kept in protected environments under human care and which enable us to learn about their food habits and behaviour. All animals in a zoo are provided, as far as possible, the conditions similar to their natural habitats.
