Symbiosis

Symbiosis is a long-term relationship between two species in which at least one of them benefits.

There are three main types of symbiosis.

First is mutualism, a win-win relationship where both species benefit. For example, the clown fish protects the sea anemone from its predators. In return, the sea anemone’s stinging tentacles keep the clownfish safe from its predators.

The second type is commensalism, where one species benefits while the other remains unaffected, like the barnacles attached to a whale’s skin. The barnacles get a free ride and a place to live, and the whale isn’t affected by it.

The third type is parasitism, in which one species benefits at the expense of the other. A good example is a hookworm living inside our small intestine, feeding on blood and making us sick.

All these symbiotic relationships reveal how species in nature survive by helping, sharing, or even taking from one another!
