Commensalism

Orchid in a Tree
Jennifer C. Estigoy


Every single day in our world, the drama of life unfolds even in the most ordinary setting. Take the lowly tree in your backyard, under the tree; you may see grasses and even variety of insects. It may not be obvious to you at once, but these plants and animals interact with each other. You may find some insects feeding on the leaves or you may notice how butterflies and birds avoid you when you go near them.
                Your backyard may also have a source of water, unpaved soil, stones and rocks. The plants and animals you will interact not only themselves, but also with non-living things such as the soil, water and air.
                In an ecosystem, certain relationship exists. One symbiotic relationship is commensalism. Unlike termites, orchids the attached to a tree do not affect the tree at all. The tree provides support to orchid but it does not gain or lost anything. A symbiotic relationship where one individual benefits from another without causing harm.
