1. Botanical gardens, museums and zoos are taxonomical aids which can be used to study biodiversity.
2. Botanical gardens have a wide range of plant species that are protected and preserved which can be observed and studied.
3. Museums help gain information about various plants and animals that are preserved and may even be extinct. They act as reference hubs for biodiversity studies.
4. Zoos provide information about various animals.
They also harbour certain endangered animals and help us understand the role of biodiversity conservation. They can also be visited to study the food habits and behaviour of animals. Hence, we should visit botanical gardens, museums and zoos.
