The video explains symbiosis, a close long-term relationship between different species, focusing on mutualism, commensalism, and parasitism. Mutualism benefits both organisms, as seen in the microbiome, termites, and yucca moths. Commensalism benefits one organism without affecting the other, exemplified by hermit crabs, mites, and orchids. Parasitism benefits one organism at the expense of the other, with examples like lampreys, worms, and a fungus affecting ants.
