What is Symbiosis?

The video tutorial by Leo explains symbiosis, a relationship where two species coexist, with at least one benefiting. It covers three types of symbiosis: parasitism, where the parasite benefits at the host's expense; commensalism, where one benefits without harming the other; and mutualism, where both benefit. Examples include ticks and cows for parasitism, barnacles and whales for commensalism, and clownfish and anemones for mutualism. The video also discusses obligate and facultative relationships, where partners may or may not rely on each other for survival, and concludes with an example of inquilinism.
