Epiphytes are plants that grow on other plants, typically trees, without harming them. They obtain moisture and nutrients from the air, rain, and debris that accumulates around them. Common examples of epiphytes include orchids, ferns, and mosses. They are often found in tropical rainforests, where they thrive in the humid environment. Unlike parasitic plants, epiphytes do not take nutrients from their host plants. Instead, they use their host for support, allowing them to access sunlight in the canopy. This unique adaptation helps them survive in competitive ecosystems where ground space and resources are limited.
