What animals lives on a plant?

Many animals live on plants, including herbivores like caterpillars, which feed on leaves, and various insects like aphids that extract sap. Some animals, like tree frogs and certain birds, use plants for shelter and nesting sites. Additionally, epiphytes like orchids and bromeliads grow on the surfaces of trees without harming them, relying on them for support. These interactions highlight the diverse relationships between plants and animals in ecosystems.
