Answer:
1. Flowers rely on bees to cross-pollinate their female plants. When bees feed on the pollen, their body picks up excess via their pollen-collecting hairs, which is then released when they land. Pollen act as the flower's seed, which is mandatory for the survival of that flower species
2. Orchids, like any pot plant, absorb carbon dioxide from their surrounding environment and release oxygen back into the air. As well as their uniform natural beauty, Orchids have also been claimed to offer health benefits. Some cultures even believe that orchid flowers as a healer of fever, diabetes, kidneys and lungs
3. Commensalism. A commensal relationship occurs when one species benefits from the close, prolonged interaction, while the other neither benefits nor is harmed. Birds nesting in trees provide an example of a commensal relationship (Figure 1). The tree is not harmed by the presence of the nest among its branches.
