Zoos are typically built using a variety of materials, including concrete, steel, glass, and wood. Enclosures for animals may be constructed with strong fencing or barriers to ensure their safety and containment. Additionally, zoos often incorporate natural elements such as rocks, plants, and water features to create environments that closely mimic those found in the animals' natural habitats. Overall, the construction of zoos focuses on providing safe and comfortable living spaces for the animals while also allowing visitors to observe and learn about a wide range of species.
